ThermoProTP50 Digital Hygrometer Indoor Thermometer Room Thermometer and Humidity Gauge with Temperature Monitor

The product is very compact and nicely designed. The one I got seems reasonably accurate (I don't have the proper equipment to validate 100%). I can say that at least the temp part of it is pretty close to what my digital home thermostat shows - 73.8 degrees (this one) versus 73 degrees. I would also mention that my Oregon Scientific clock / thermometer also shows ironically exactly 73.8 degrees. Compare that to the digital atomic clock I have in my office which is saying the temp in here is 75.2 degrees which I don't believe to be accurate (I don't know how well the hygrometer measurement is - however based on what was described on the local weather report it seems pretty good - I don't have another means to accurately compare it though). I also don't really have a way to more accurately assess the temp measurements (I'm pretty happy it matches what I consider my best existing temp measurement device I own) so I'm going to go with what I can accurately describe. This unit is relatively small and seems well designed. Drop a AAA in and you're good to go. The design on this seems well thought out. There is a little foot in the back of it that allows it to stand. It also seems durable. When I was comparing it to my thermostat I had it sitting on a stand about 5 1/2 feet above the floor. It fell and still is working without issues (admittedly it fell on carpet but a lot of things wouldn't survive that - this did and it didn't change the measurements being displayed). There is also a built in magnet to allow it to be attached to any object that a magnet can attach to. I would also add that when I grabbed this the temp quickly changed (which seems reasonable because my body temperature is well above the ambient temperature here - just pointing this out because I was impressed with how quickly the temp reading started to change). I don't think the temp reading goes down as quickly though (I mentioned above it matched the 73.8 degrees my other temp monitor showed and after I grabbed it in my hands the temp jumped to 75.4 degrees and it took a while for it to get back to what I believe is the current temp. It also has the min and max readings on both humidity and temp. I would sum up in saying I'm really impressed with the unit at this price point. Oh and last but not least the company reached out to me (with no query on my part) to make sure I was satisfied - that means to me they care what customers think about their products.

very accurate. battery life seems to be infinite. what more can i say. it’s a good and inexpensive product

This works Great since I got it (I’m using it in a green house) it gives me accurate reading every day. It was very easy to setup and temperature my green house. Great brightness specially at night and it works perfect in my phone app. It was a great purchase

Essentially, if a thermometer/hygrometer works and seems relatively accurate, I'm going to be satisfied. In addition to meeting that benchmark, this thermometer has all the features I was looking for: It measures both temperature (in either °C or °F) and humidity; keeps track of the highs and lows for both readings until you push a button to reset them; it's compact and easy to read. The unit has a stand which folds out from the case and a magnet on the back if you want to attach it to a metal plate, refrigerator, etc. I would have preferred a hook or screwhole in place of the magnet...or in addition to...but I won't take points off for that. It uses one AAA battery and has been working fine on a NiMH rechargeable for the past 7 or 8 weeks.The one flaw I've found is in regard to the magnet. It is mounted in a recess on the back of the unit, attached by an adhesive strip. I know that because, when I last removed the unit from the metal plate to which is was clinging, the thermometer came off but the magnet stayed behind. I could push them back together but I can see that before long I will have to use a stronger adhesive or the magnet's going to be coming off on its own.I'd still recommend this unit but be prepared to do a little handywork if you're using the magnet.

Gives me the info I need for my plants. Works well.

It’s a tiny device, perfect for me. The numbers are large and bold enough to be read about 5 feet away by this near-sighted person 😊. It seems to be accurate so to test the humidity in my bedroom I waited until it acclimated (about 15 minutes). The building’s heat is on, my windows closed and I could tell it was dry by the sinus pressure in my head. I turned on my humidifier and watched to see how the gauge would react. Gradually, the humidity numbers went up to 32. My bedroom is very small-maybe 12’ x 12’ or so-with a small closet and 2 windows facing south-east. Outside temperature was around 50, indoor reading was 74. I have the gauge out of ambient breeze, attached to the wall steel stud by the magnet (could be a lil bit stronger). About 15 minutes with the humidifier going on full (it’s small, also), the gauge registered 32 at the “comfort-able” level with a happy face. I turned off the humidifier again opened a window. In about 5 minutes the gauge registered the temperature drop as well as the drop in humidity.I’m permanently physically disabled with a LOT of pain that worsens according to barometric pressure, heat/cold and humidity. I’m also asthmatic so I need to monitor everything to help myself get through daily. I hope this will continue to work.It is very small, fits in the palm of my small hands. So it won’t be an eyesore.There’s a stand in the bottom back to set it anywhere. Plus the magnet on the back allows you to stick it wherever there’s a metal surface. Don’t put it on a fridge, A/C unit, near anything the generates heat or cold or in a window, in the sun or whatever a breeze passes because the readings won’t be accurate. You want an area that’s off to a side of activity to get correct readings.

Works perfect! Easy to set up, already a big help in regulating my greenhouse temp.

This is a nice unit for the money
