InkBird ITH-20
I needed a temperature/humidity indicator for my basement to see if there was any big difference between the upstairs living area and the basement. I already have indicators for the main floor of the house so I tested it out against my Honeywell thermostat and the Taylor Humidiguide. When I checked against the thermostat it that was very close, a bit higher on the humidity but good on the temperature. So then I checked it against the Taylor Humidiguide and dang, it was spot on both the humidity and the temperature, so Iâm happy. The unit is not back lit so you have to read it in under some sort of light source. The display is nice and big, easy to read, even from a distance, and fills most of the screen on this compact sized unit. I mounted the unit on the wall in the basement, convenient to read and control. Once you set it in place you should not have to take the unit off the wall to adjust it, only to change the batteries. Very good value for the money, again easy to read and accurate, isnât that what you want!

Fantastic Room Monitor
I have reptiles and invertebrates and have been using Inkbird Thermostats for them for years, but recently I wanted a way to monitor the ambient temps in my reptile room to better gauge what heat bulbs and such I need to use. Bought this little guy and it works like a champ. I monitored it with some other equipment for the first week and it was always spot on. Very nice to be able to see what the room temp dropped to over night and what the humidity is reading. Was very inexpensive too, so well worth the cost.

works good.
I am was needing one for my basement. I have an acurite one already, but wanted one up stairs as well as down stairs to monitor my humidity and temps. With reading the reviews of that were given a 1 star, I thought I would test it out against the one that I have ( which has high reviews). It seems to be fairly accurate in caparison. for the Price that was spent for this, it is great. My next check was sitting it up stairs close to my thermostat. I have my thermostat set to 76. it does not give humidity so it is just based on my temperature. It is very user friendly. on the back all buttons are well marked. I have not mounted it on a wall, but have been using the stand, which supports it very well on flat surfaces.The only thing that I wish it had was a magnet on the where the batteries go. but that can be easy done as a DIY project.

Compact and easy to set up.
Very cool little unit! Way smaller than I thought it would be (about the size of a matchbook, if anyone knows what that is anymore), but very easy to use. As soon as I out in the two AAA batteries, it read the relative temperature and humidity of the room. Bright display, easy to ready and simple to use. Plug some batteries in, set your units and youâre off! Will be useful in monitoring garage temp and humidity when brewing and storing beer.

One year if you’re lucky!
Most of these only work for about a year, if you are lucky, and I have had over ten different ones from Amazon.

Very handy little devise
Very versatile and accurate. I like that it can be wall mounted, but also has a kickstand to keep it mobile. Very intuitive and easy to use. Best part is the readout screen can be turned off, while the devise continues to record measurements, so it wonât burn all its juice quickly.

Hydrometer on the fritz
This initially read temp and humidity correctly, but a few months in the hydrometer went on the fritz. It now sometimes reads 100% humidity, which just isn’t possible in our arid desert. The thermometer continues to operate as expected. The display is nice, I just liked it more when both readings worked.

Se puede poner en °C o °F. Se puede tardar unos minutos en medir bien la temperatura, pero es porque su uso ideal es tenerlo fijo. Tiene una base para mantenerlo de pie o un hoyo para colgarlo en una pared.Funciona bastante bien. Ocupa un par de baterÃas AAA (no incluÃdas) por si piden uno.
