Exo Terra Analog Hygrometer

I have two of these in separate vivariums in the same room. I've had one for the better part of a year and have had the other about 4 months. They have been working fine for me. I love the color coding that makes them easy to read and interpret. I don't feel the need to chase humidity down to the single percent, but rather follow trends and correct conditions as needed. While there may be times when the needle doesn't seem to move much, when the house become dry in the winter and supplemental humidity is needed, these little hygrometers help me keep viv humidity in the right range. If you need to move these they can be moved. I used a razor blade to remove, removed all the backing and then hot glued in the new position. While the included tape is relatively safe in a viv, with snakes fully cured aquarium safe silicone or hot glue is even safer. Just be careful to use small amounts of glue on the four raised pads. If you block airflow it will not work right. What's not to like about useful, inexpensive and easy? Love these.

These seem spot on. I am curing plant material in Mason jars, and am using a 62% Boveda pack. I got 4 of these and all 4 are dead on at 62%. The great part is that they fit right inside the jar, and because I am using them in clear jars, these small guys fit right inside, and I can monitor the humidity without opening the jars. They come with a round foam sticker to stick on the back of the unit, but if you pop out the little circle in the middle, you can use that piece of the two sided sticker to attach it to the inside of the glass facing out. They work perfectly for my intended purpose.

Works well, but even though I ensured surface was clean and dry prior to application- the adhesive did not last more than a day or so. Considering its purpose is to measure the level of humidity, I did expect moisture resistant adhesive or another option to mount. The tank it was being used in did not require high levels of humidity, so I can’t imagine other customers are having better luck.

Ordered quite a few of these for my cages and they work great

I bought this to keep track of the humidity in my house, which I know it's not designed for. I wanted to know if I needed to put my humidifier on over the winter and this seemed like a cheap option. We ended up using the humidifier and think that's the right call but it was hard to get an accurate reading off of this.

Works well

I have a rainforest terrarium. If the humidity gets too low, the life inside suffers. I have digital hygrometers, but they do not tolerate prolonged exposure to high humidity. I wanted an inexpensive analog hygrometer for permanent residence in the terrarium. This was inexpensive. It has one job though (measure humidity) and it fails badly. It is responsive to changes in humidity, somewhat, but the readings are so wildly inaccurate, especially at extremes, that it is useless for my purposes. At ambient summer humidity (currently about 75%) it reads 60%. In the terrarium (100%) it reads 75%. 15-25% off is a shameful degree of inaccuracy. It is not adjustable, so either I make the adjustments mentally and trust the terrarium life to a woefully inaccurate device, or I continue my search for a competent analog hygrometer. If it is convenient for me to return this I will. Otherwise it will go in the trash. I’m disappointed with this device in particular and this brand in general.

I purchased this a king with several other meters, some with temp included and some digital. Used the above do 75% RH test. After 36 hours it sat at 73% which is accurate within 2%. Compared it to serval others that I calibrated with the salt test so I know it is accurate. Despite what tons of these reviews say what I learned is the large majority of any of these hygrometers and temp scales will be within 5 degrees accuracy which unless your in a lab or something crazy will work just fine for almost all applications. I wouldn’t get to hung up on what model or type, just so long as you test it and it is fairly accurate. I wanted this guy because it was super cheap, came with adhesive and gives/has a color background that I can see the humidity level on whether or not visibility is good or not inside enclosure.

Värdelös. Står stilla. Visar fel

Ich brauchte für mein Terrarium mit den Orchideen schnell etwas einfaches. Das lag daran, dass das Terrarium nur geliehen ist. Ich habe etwas gezweifelt. Zum einen ist es keine unbekannte Firma und zum anderen waren die negativen Kritiken recht deutlich. Nun ich habe es doch gewagt und zweifelte den erste Tag nach der Anbrinung. Doch schon am zweiten Tag musste ich feststellen, dass es wunderbar funktioniert. Das Hygrometer reagiert sehr schnell und auch sehr fein auf jedwede Veränderung. Auch der Kotrolle durch ein anderes Thermometer hält dieses stand, sogar ohne größere Abweichungen. Hier lagen die Abweichungen aber eindeutig daran, dass das Kontrollgerät auf dem Boden und damit auf nasser Drainage stand und dieses an etwa 15 cm über den Boden an der Scheibe befestigt war. Ich kann mich nicht beschweren und für meine Zwecke vollkommen ausreichend.

Worked perfectly well with good enough accuracy for hatching Guinea Fowl eggs in a home made incubator.

Hydromètre plutôt lisible et semble fonctionner correctement pour un prix imbattable (moins de 3€) Parfait pour mon petit terrarium! Seul point négatif la fixation se fait par ruban adhésif, j'aurais préféré une ventouse (plus pratique pour l'entretien)

Works great for the terrarium
