AcuRite Digital Hygrometer with Indoor Monitor and Comfort Scale (01083M) Room Thermometer Gauge with Temperature Humidity, 3 x 2.5 Inches, White

Read through nearly all the reviews and go along with the majority view - this appears to be an accurate and sensitive device. I am using it to measure residual damp in a bedroom ceiling. The humidity range in my case went from 43 to 63 but never higher. I am unsure whether I will need to calibrate but that is a useful option. Instruction manual contents were unclear on toggling from 24 Hour to All time level - but then I was told the answer was on the cover of the manual not inside !

Very easy to set up and is great to use in a room with accurate readings.

I got this thermometer as I am not convinced the Hive thermostat we have is accurate. The temperature has been accurate so far and the display is large enough to see from about a metre away clearly. It also has the option to calibrate.

Easy to read used in my lounge very accurate

Accurate and good price

Bought this about 2 years ago and still on the same battery. Very accurate and no problems. Thinking of getting a second one for the caravan.

The temperature reading was completely out. It kept insisting that it was only 4C in my centrally-heated house. Placed in a few different places and finally in the kitchen in the warmest part - the device then claimed it was only 3C after 24 hours. It wasn't even 3C outside! This is a useless piece of junk!

I paid a bit more for this than some cheaper models available, in the hope that it would be more accurate and robust. Alas, after just a year of use, the display has stopped working on the humidity numerals, making it impossible to read. Changed out the batteries and put new ones in, made no difference. ACU-RITE has become ACU-WRONG. That was an expensive £26 lesson I've learned. Just replaced it with 4x smaller models for the total cost of... £3.99, for all four. Working perfectly so far. I'd avoid this VERY expensive ACU-RITE, as other reviewers have had similar experiences in even shorter timeframes, it feels like a rip-off charging £26 for a so-called premium Hygrometer that is likely to break as soon, if not sooner, than a £2 one.

Excelente produto, muito preciso na temperatura e umidade, logo irei adquirir outro.

A smidge smaller than an audio cassette or one and a quarter USB's high LOL. What a great looking unit. I recently had a new furnace and humidifier installed. The main new full featured digital thermostat gives me temperature and humidity readings on the main floor; but, I also need to know the same downstairs in the family room so I opted for this AcuRite 01083M Pro Accuracy Temperature and Humidity Monitor after perusing others. It met all my check marks as I know perfect doesn't exist for several reasons, having worked in the industry (unless your room is a controlled sealed bubble per se). Therefore, good and in this case very good does a great job for me. A quick glance at my family room bar fridge (where an integrated magnetic mount holds this unit), and I now have a temperature and humidity reading that is almost bang on, having tested it from the position of my thermostat upstairs. Besides, my main one is wired and costs in the lower mid triple digit category, and I'm going to compare apples to oranges? Nope! But, both of these units are closer to apples to apples and oranges to oranges. They are that good. Why does that matter? I can now set the humidifier to meet my requirements that will keep my acoustic guitar and electric guitar happy. Remember I said perfect doesn't exist? 40% - 50% humidity is usually recommended for the guitars to prevent neck warping, cracking and more, but that can be bordering on too high for some homes, so I keep a happy medium around 40% - 42% when they aren't humidified in a case. A back light? That would be handy, I suppose, but I'm guessing battery usage would increase, and I like this slick modern design Temperature and Humidity Monitor layout, size, and features. This AcuRite does the trick. Recommended.

Es justo lo que buscaba. Registra la temperatura y la humedad de la casa todo el día y si cumple su función. Lo recomiendo.

Very useful device for checking room temperature. Would be great if it could be more easily calibrated.

It work very well, I can leave it any where inside the house to monitor the Temperature & Humidity.
