ThermoPro TP55 Digital Indoor Hygrometer Thermometer, 4-Inch Temperature/Humidity Monitor with Touchscreen and Backlit, Indoor Room Thermometer/Humidity Meter for House Home Greenhouse

Accurate and Sensitive, with Easy Setup
I’m actually going to take a bit of time and write a review, because I really think this product deserves it. I’ve only had it for around two weeks, but so far, so good.I got this wireless thermometer for a bit of an unconventional purpose; as a wireless way to monitor temperature and humidity (mainly humidity) in my Crested Gecko’s vivarium. The setup I have really doesn’t allow for devices with cords/probes, and reviews for thermometer/hygrometers that were actually made for pets were pretty dismal. So, after seeing this new ThermoPro product with great reviews, I decided to give it a try (my gecko has a pretty big viv and he loves exploring new things, so the addition of a small sensor wouldn’t bother him).The outdoor sensor seems to be working great thus far, no major erratic swings in readings at all (unless I do something to make it change, like misting the viv). It’s waterproof, but you do need to have it upright so that water doesn’t enter the sensor at the bottom. It has a little hole at the top that I threaded a paper clip and string through so I could hang it on a vine. It also has a bright red light that flashes every 30 seconds or so when it sends data to the main monitor, which I worried might bother my gecko, so I carefully covered the solid plastic and red light with dark painter’s tape, leaving all the sensors and compartment-opening-points still exposed, and now the light is not noticeable at all, unless you’re really hunting for it at just the right angle. Adding the tape did not affect the temp/humidity readouts at all; they stayed the same after applying the tape as they were before.The main readout monitor itself is really nice. It took me a few tries to really get the hang of the controls, but since there’s only 3 buttons to tap, it’s not that hard. Touch screen is hyper-sensitive, and the backlight (which I thought I would never use) actually is handy since it’s positioned in a room that gets hardly any light after sunset, and the numbers can be hard to see if I want to check them in the evenings. But this room is exceptionally dark; the contrast on the readout is more than enough to be easily read in a normally-lit room.As far as accuracy goes, I have to say that it is accurate simply because it says the same things several of my other gauges do. I have one mercury-style thermometer, one analog thermometer, one thermometer/humidity laser gun, and one analog hygrometer. Between all those devices, the numbers really don’t change. If anything, I would say my temp gun is the least accurate, but only because it isn’t measuring the temp of the air, but the temp of the material it’s pointed at, which varies greatly. Therefore, its accuracy is not quite in the same category. At any rate, I just got up and checked all the gauges, and they’re identical to what this ThermoPro wireless device says. I find it hard to believe that so many different devices could all be wrong in the exact same way, so I believe this one is accurate.Setup was fairly quick and simple, and took way less time than the directions indicated; so much so that I set it all up twice just to be sure I did it right the first time. Same results, so it looks like it’s all correct.All in all, it’s shaping up to be a great little device, and I’m glad I got it. It gives me peace of mind to know that everything’s the way it should be in my gecko’s home with just a quick glance at the screen (which I placed on a nearby bookshelf), and I love knowing the temperature/humidity of my own home, since I did not have any sort of fancy thermostat before (old baseboard heating). I also like knowing that multiple sensors can be registered, so if I ever want to actually put one outside, I can get one and easily do so. If anything changes, I will update this review, but as of right now, I am very happy with my purchase. 🙂

من يوم مااشتريتها مااستفدت من القطعه الخارجيغير شغالهوغير فعالهيجب ان تلصق القطعتين بجانب بعضها حتى درجة الحراره الخارجيه يتم قراتئهاوهذا الشي غير عملي وغير فعالكيف احصل على درجة حراره داخليه وخارجيه اذا!!!السعر مبالغ فيه

Vivo en costa y con una humedad muy alta. Lo uso para controlar los niveles junto con mis deshumificadores.

Excellent Hygrometer and Thermometer. It seems to provide a very reliable reading. Batteries come included. The temperature readings can be changed between Deg F or Deg C. I like the magnet at the back that makes it installing easier on a mettalic surface e.g. a fridge door.
