How can we do it once purchased?** A: I am not sure if you can use this to test the pH if a person. Perhaps by putting it in sweaty skin. You should call manufacturer to see if they can answer your question. **Q: can i use this meter for cheesemaking?** A: Don't see why notCheesemaking websites list similar ones, maybe less precise than this but same technology **Q: Can I use for stiff dough?** A: Yes you can. This can read liquids and solids. I use mine to measure the ph of cheese curds and whey. **Q: I have a very similar meter but it is "ph110" instead of "ph100." will this "ph105" sensor work with the "ph110?"** A: Yes the PH105 is the replacement pH electrode for both the PH100 and PH110. ## Customer Reviews ### ⭐⭐⭐⭐⭐ just the job we use a few of these and ... *by C***S on 11 December 2015* just the job we use a few of these and always does what it is supposed to do ie tells us the PH of the water leaving the factory ### ⭐⭐⭐⭐⭐ Five Stars *by M***H on 15 May 2015* Just what i needed ### ⭐⭐⭐ It does its job but it doesn’t last *by M***M on 25 March 2024* The pH meter does its job but it lasts only a couple of months. Being that the probe can’t be replaced, I think it’s expensive. I wish the readings were more stable as well cause it takes time to show a reading and even so it keeps changing. ## Frequently Bought Together - Extech Instruments PH100 Waterproof pH Metre - ph buffer 7 300ml & ph buffer 4 300ml growth technology free 100ml formulex --- ## 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/50057485-extech-ph100-waterproof-exstik-ii-ph-meter-kit-flat-electrode](https://www.desertcart.at/products/50057485-extech-ph100-waterproof-exstik-ii-ph-meter-kit-flat-electrode) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-26*
