ThermoPro TP50 Digital Thermo-Hygrometer Indoor Room Thermometer with Recording and Climate Indicator for Room, Climate Control Monitor

Firstly huge thanks to ThermoPro for designing tech that just works out of the box, insert the batteries and you're working. Similarly the App just downloads and runs and picks up the device straightaway, no fuss. If only all tech was this straightforward.I wanted to monitor the temperature in an adjoining outbuilding where my water supply enters the building from a borehole. I was concerned about it freezing and bursting the pipes. However, there's a substantial (18" - 24") stone wall between the outbuilding and the kitchen. I wasn't sure the Bluetooth would get through but there are points where an air vent and pipes come through the wall. The good news is that I can read the temperature on my Nokia and my iPad.I believe it's accurate enough for my needs. I put it next to two ThermoPro TP50 units that I've had for over two years and once they settled down, took a few hours, they were all in agreement within the accuracy claimed for them, temperatures were within 0.2 'C, humidity within 3% of each other. The TP50s have run 24/7 for two years on the original batteries and never missed a beat monitoring humidity when we're drying clothes indoors with a heated clothes airer and a dehumidifier. Overall I'm very impressed with ThermoPro devices.

what a nice surprise to see a product that is good value and works out of the box, Well you have to put battery in. nice and simple seems to work well. gives high and lows of temp as wll as current. Clear big numbers. has a magnet on the back so i have mine on the fridge door.

A nifty little product that lets you know the humidity and temperature of a room. It's accurate within a degree or so from what I have monitored, nice big icons and text, so it should be fairly easy to read from a distance..I have mine using the mini stand on my desk in my room.Nice build quality, but I believe it could have done with a backlight for viewing during the night. It seems pretty sensitive to temperature and humidity changes.

I have had a few of these devices for a decade but they recently stopped working.; knowing the temperature and humidity in different rooms has been an interesting exercise round the house, especially as we refurbished and improved insulation in different areas.They work straight from the box. Insert the supplied batteries and they instantly spring into action. No fuss, no settings - just data. That’s a big plus.The are improvements on my previous versions, e.g. the text is clearer and the show the minimum and maximum of each datum.Recommended.

A cool little product that lets you know the humidity and temperature of a room. Pretty accurate, nice size with big icons so easy to read from a distance..I have mine on the side of the fridge as it's magnetic bit it does get moved around the house every now and then...it has a nice little stand so it can be put anywhereNice build quality with a nice bright screen that you can see. It seems pretty sensitive to temperature and humidity changes.

Both of mine lasted around 3.5 years on their original included AAA battery. Memory of past readings doesn’t retain with a battery swap, even if you do it really fast unfortunately. Reading accuracy seems pretty good, around the same as my dehumidifier and central heating sensors. I find them useful in the winter for indicating when you need to open windows and let in some fresh air or turn on the dehumidifier

Excellent value for money. Have now bought 3 of these to use in different areas. I needed something to keep a record over time of humidity and comfort levels in areas that are be prone to mould.Very neat and a clear display with touch sensitive backlight. Very easy setup. Good mounting options for hanging on a nail/hook, has a flip-out stand built-in, and has a strong flat magnet.The Thermpro app is excellent. Doesn't need too many permissions, and communicates with the device by Bluetooth over a wide area. The data records are easy to read, giving minimum and maximum readings for both temperature and relative humidity, and you can view history by hour, day, week, month, or year. Holds up to 2 years data. Individual devices can be renamed, and hold their own separate data logs.It does everything I needed it to, and at a very reasonable price. Highly recommend if you are having damp related issues, as this should give you a good understanding if the problem is structural or environmental.I'm not sure how long the 2x AAA batteries will last, but time will tell. There's a simple built-in battery level indicator, so you'll be able to see when the batteries need refreshed. That's fine for my needs.
