ThermoPro TP55 Digital Room Thermometer Temperature and Humidity Monitor with All Time or 24hrs Max and Min Records for Temperature and Humidity Baby Room Thermometer with Large Backlight Touchscreen

Great piece of kit Nice large display which is easy to read and function buttons easy to use and understand. Give a clear and accurate reading of temperature and humidity. Has backlight for viewing display A really good purchase Recommend

These are good units. Easy to read and update quickly. They are a good size without being obtrusive and I believe are good value. They seem to be accurate both with temperature and humidity.

Good item with all I need on the front screen. Cool blue light is useful. Screen can be difficult to see at an angle or when battery gets low.

This is an item you don't know you need until you buy one, (I have them in each room). I was surprised to find my 12 year old house is above 60% humidity, despite trickle vented windows, especially downstairs. This knowledge has saved me making a huge mistake. I thought my house was on the 'dry' side, as there is no visible condensation or mould and I was contemplating buying a humidifier. Now I know I may need the opposite. Having these useful little devices gives you the opportunity to monitor each room. I now open windows and doors for 10 minutes to exchange the air twice a day and I can actually see the humidity levels lowering. Very effective and worth purchasing.

Excellent product works great very accurate and I would recommend this product.

My purpose for this device is to simply know the rough temperature and, more importantly, humidity in my flat, especially during the cold winter months. I don't own a greenhouse, a terrarium, a vine cellar, or a similar thing requiring more "professional" reads. Reading the reviews on this hygrometer and many others, I noticed that they all have people complaining about bad readings. Since I couldn't find a single one with a reasonable number of reviews (say, 100+) without someone complaining about this, and because it's a fairly cheap device (16 GBP at the time of this writing), I decided to get 2 of them for the 2 rooms I'm most interested in, keep them together for a day, and compare. I'm guessing that the chances of 2 of them being equally faulty are very slim, given that most of the other reviews are very positive. In case that these two proved to be very inconsistent, I would've requested a replacement for both, without worrying which one is the faulty one. I would suggest anyone buying these to use this approach, unless you have another device (especially hygrometer) to compare with. The results of the experiment can be seen on the accompanied image: - quite consistent current humidity (only 1 percentage point); - some discrepancy in the lowest measured humidity (4 percentage points), which is to be expected of any such device; - fairly consistent current temperature (under 0.5C apart, and usually it's less); - 24h low/high shows a bit bigger difference (1C) in the lowest measured temperature. My conclusion is that both of the devices work fine, unless one needs super-precise measuring, in which case you need to go way above this price range. As for the other features: the setup is trivial (it consists of putting the supplied batteries in and, if Fahrenheits are your thing, clicking the icon on the screen), the backlight is quite pleasant, the screen is very visible, the magnets on the back seem to be quite stronger than a device like this needs,... All in all, the device does very nicely what it is advertised do. Not having checked the dimensions prior to buying, I expected considerably bigger devices (the impression I got from the obviously doctored product images) and I was pleasantly surprised when they arrived. In my opinion, the size is just right to make them very readable, yet quite elegant (although, I do admit that this is a matter of personal taste). These were delivered to me less than 2 days ago (2nd Nov 2018), so I cannot speak of their durability. However, if this review remains unedited, you can be sure that this didn't prove to be a problem since. To conclude: These are a good value for money, and I would recommend them to anyone with similar, non-professional needs.

I love these. We had a very, very wet house, with water pouring down the windows in the winter. A friend persuaded me to buy one of these to help research the issues of the house. I was convinced it would be complicated and did not take it out of the packaging for over a year! One day I got brave & was astounded. So easy! Tells you everything you need to know the second you put the batteries in! Everything you need is just on the screen & very obvious. If you want more, the touch screen gives easy & instant extras. I can see what the humidity is and the temperature. Also what it was in the last 24 hours max & min. I can have centigrade or fahrenheit with one touch of the screen. It will even light up if I want it to for night viewing. I could not ask for more. I brought a dehumidifier (arete two, 20 L) which also worked really well and very easily. The house started to dry out at once & within 2 weeks it felt dry and no more water on the windows. I brought one of these little toys for each room! I have put them all in one room to test accuracy and they all agree which is reassuring. They also give the same reading as the dehumidifier. I am ridiculously happy! This is a very useful and very easy to use tool

I bought two of these to keep track of the humidity level in the lounge and upstairs bedroom, really good and accurate devices.
