It worked so well - basically you 'set it and forget it' - that I've bought a second unit to handle temperature control in my dispensing cabinet (kegerator) build. FEATURES The idea of the Inkbird is really simple to understand. You enter the temperature you want it to maintain and you place the probe somewhere for it to measure that temperature. You enter the lowest that you're willing to tolerate the temperature being off by and if the measured temperature falls below that point it will activate the socket marked 'heating' until the measured temperature reaches your ideal point. Similarly you enter the highest temperature you want to tolerate and if the measured temperature breaches it then it will activate the socket marked 'cooling'. All you need to do is plug a heating device into the socket marked heating and a cooling device (e.g. a fridge, freezer) into the socket marked cooling. It is not mandatory to have both plugged in at the same time, for example I don't need cooling in the depths of winter so I just plug the heater in. The Inkbird has a safety feature that allows you to specify the minimum time between activating the cooling socket. Fridges and freezers can be damaged if their compressors are cycled too quickly. This feature prevents such damage, and in the event of power loss it will assume that cooling was previously on and will not reactivate it until the safety time has run down - nice. Another nice feature is that it has a buzzer alarm for high and low temperature thresholds in case your heater gets stuck on I guess. I've never used that. You can also calibrate the thermistor probe by entering an offset if you find that it drifts over time. ACCURACY I have an ETI thermocouple with recent calibration certificate that I compared my ITC 308 units to. The first one was only 0.1C off, the second one was 0.2C off. Those differences are within the margin of error of the probes. That's rather impressive and of course once I'd entered the offset into the ITC 308's calibration feature the difference was zero. EASE OF USE Hold down SET. Cycle through the different options using up/down to enter the numbers. Hold down SET when you're done. All settings are remembered when the power is cut. PROBE CABLE LENGTH 2 metres. BUILD QUALITY It feels very tightly put together. All cables have tough rubber strain reliefs at the exit from the unit. There's a handy screw/cable-tie hole at the top. The plug is UK 3-pin. WARRANTY 12 months TIPS Use the lowest power heater you can get away with. If it's too powerful you'll get overshoot as the heater will still be hot long after the power has been cut. Try to measure what it is you want to control rather than the air around it. Again this will avoid constant cycling as the air changes temperature rapidly before whatever it is you're trying to monitor 'catches up'. SUMMARY I'm super happy with mine; I guess I must be if I came back for a second one and I echo the positive comments that the other home brewers are saying about the ITC 308. Review: Easy to use and has a few useful features that make it preferable to my STC-1000 - The Inkbird 308 is an easy to use, plug in and go temperature controller that I got to supplement my current STC-1000 controller. I use both for home brewing, either holding a fermentation fridge at the right temperature, bringing strike water up to temperature or cold crashing. It has a few advantages over the STC, a) You can see the current temperature and the desired temperature at the same time. A few times I've used my STC to get strike water for the mash ready, then forgot to drop it down to mash temperature and basically killed the mash. b) It's easier to program than the STC and it can be done with one hand. The STC requires you to hold down one button while pressing another while changing settings - I know a brewer that has a problem with one of their hands that can't program the STC. The settings are also abbreviated to letters, e.g. ts for temperature set rather than just numbers 1 to 4. c) You can set the differential from the temperature you want separately for heating and cooling which really is great if your heating or cooling system causes swings. You might want it to start heating when the temperature is half a degree below your required temperature, but not want a cooler to kick in until it's 4 or 5 degrees over - the STC doesn't let you do that. d) The quality of the temperature probe wire is much more rugged and twice the length of my STC probe's and the replacement I bought. This may be because I bought a knock-off STC. I stick the probe to my fermenter under a wadge of blu-tak and just with reasonable flexing the wire shielding split next to the sensor. I didn't notice this and humidity got into the split and caused changes in resistance meaning I had to recalibrate it all the time. I thought the STC itself was broken before I tracked it down. e) It has a high and low alarm feature which I find useful when doing a mash. I don't have a good mash tun so I set the low alarm to 65c and when it goes off it lets me know to add a bit of hot water. f) It's plug and play! You won't run the risk of electricuting everybody by not knowing how to wire it up. g) It's plug and play #2! You won't risk eye and limb damage trying to Dremel out an aluminium hard drive enclosure to fit it into and all the sockets. Seriously, the sparks burnt my decent jumper when I made my STC enclosure, and the number of disks I went through was shocking. In the picture I've got them lying together but actually have the 308 and sockets mounted on the wall and it feels really solid. Overall even though it does the same job as my STC-1000 it does it slightly better and I sort of trust it more. ## Features - Easy to Use - Plug the heater/cooler in sockets at the Inkbird temperature controller, set your desired temperature and you're done. - Temperature Sensor - The temperature probe is waterproof made of food grade material, please rest assured to use in food making such as homebrewing, biltong making. - Heating Cooling Dual Output & Delay Protection - Dual relay output to connect in a position with refrigeration and heating systems simultaneously. Heating / Cooling differential function can be set to protect separately for cooling and heating for temperature control of violent change. Also, compressor delay protection for compressor control. - High/Low Temperature Alarm - With high and low temperature alarms, it is no need to pay attention to temperature changes at all times. - Widely Used - The Inkbird digital thermostat is Ideal for homebrewing, fermentation, beer/wine storage, greenhouse heater, tube heater, aquarium heater, heat mat, reptile vivarium. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E74TEPG | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 8,179 in Pet Supplies ( See Top 100 in Pet Supplies ) 2 in Thermostats for Terrariums | | Customer Reviews | 4.6 4.6 out of 5 stars (584) | | Date First Available | 13 April 2016 | | Item Package Quantity | 1 | | Item Weight | 349 g | | Item model number | ITC-308 | | Manufacturer | Inkbird | | Part number | Inkbird Temperature Controller | | Product Dimensions | 10 x 10 x 19 cm; 349.27 g | ## Images ![Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Image 1](https://m.media-amazon.com/images/I/71K-BNcjrUS.jpg) ![Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Image 2](https://m.media-amazon.com/images/I/61pNfDv5L1L.jpg) ![Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Image 3](https://m.media-amazon.com/images/I/51odTAj6unL.jpg) ![Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Image 4](https://m.media-amazon.com/images/I/61X+8QcOEEL.jpg) ![Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Image 5](https://m.media-amazon.com/images/I/81Kb0DxKUTS.jpg) ## Questions & Answers **Q: Does the seller recomend this can be used with a ceramic set up in a reptile viv? Does it act like a pulse or dimming stat or on off stat?** A: The Inkbird thermostat controller are all the on/off model. But it is also can work with the ceramic heat emitter or tube heater. **Q: Would this be suitable for a crested gecko enclosure as the heat lamp I have is very hard to maintain the correct temperature** A: I would say yes if the heat lamp you use is not relied on for any firm of light in the tank. When the temp is over your required level the power will be cut to the lamp therfore letting the heat dissipate. When the temp lowers to within 0.2 degrees of where you want to be the lamp will power back up. Normally this device will keep to within 1 degree of your required setting **Q: Can i use 2 heating equipment for the cooling and heating? I have 2 reptiles and wonder if i can plug the heat lamp in cooling and other in heating** A: The two socket outlets are controlled by separate relays. When one socket is on the other is off. The drawback is there is only one thermocouple (heat sensor) as it is designed to control ONE enclosed space not two. Experiment with two table lamps, one in each socket and use a hair dryer on the heat sensor. **Q: can someone recomend a good heater/cooler to go with this? I'm struggling to find one** A: This all depends on the size of the space your trying to maintain. Although it does work great with a oil filled radiator plugged into heat and carbon filter extraction on cool. This also helps regulate humidity. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So useful I bought another *by A***Y on 16 January 2019* I bought my first Inkbird ITC 308 about a year ago after reading multiple recommendations on the home brewing forums and I put it to use controlling the temperature of my fermentation chamber (a converted fridge).

I have been using heat pads along side a submersible heater for years, and the heat pads were not thermostatically controlled which meant that you were guessing with a timer, and having to check the temperatures several times a day. Now I don't! So glad that I found this device as it is a game changer when trying to keep a steady temperature. I have only had it a couple of days and already wonder how I did without one. Made in Germany, and seems to be of high quality. One tip when using on a home brew bucket is after taping the sensor to the outside of the bucket with masking tape, cover the whole probe with a thermal insulating material and tape this over the whole probe in order to insulate it from outside temperatures. I found that this made quite a difference to the accuracy of the sensor. ## Frequently Bought Together - Inkbird ITC-308 Temperature Controller Digital Thermostat for Home Brew Greenhouse Heater Heat Mat Tube Heater Reptile Vivarium - Inkbird IHC-200 Dual Relays Digital Humidity Controller Humidistat for Humidifier Dehumidifier --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/49008899-inkbird-itc-308-temperature-controller-digital-thermostat-for-home-brew](https://www.desertcart.at/products/49008899-inkbird-itc-308-temperature-controller-digital-thermostat-for-home-brew) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-03*
