## Description

Product Description Improved accuracy and quick updates Indoor thermometer and humidity indicator provide high accuracy (±0.5°C/1°F and ±2-3%RH) Measurements are updated every 10 seconds and displayed on the easy-to-read digital display of your room thermometer. Screen Preview The room thermometers and weather instruments have a clear and accurate display.

Reliable and durable battery The hygrometer and thermometer are powered by a standard AAA battery with a lifespan of 18-24 months, saving you time and money by avoiding frequent battery replacement.

Review: Inexpensive and Essential - Neat little temperature and humidity monitor. AAA battery supplied with the monitor, and it has a little integral stand. I live in a little very old (300+ years), solid stone cottage, and managing damp is a requirement to keep it healthy. I have learnt that old solid stone buildings need very different care to modern houses. This handy little gadget helps me know what's going on, and when and where I need to put on the dehumidifier. An inexpensive but essential bit of kit.
Review: Delighted with This Little Gadget - This is a great little thing, nice and compact and works very well. I move it around the house. You hardly notice it but it tells you all you want to know.

## Questions & Answers

**Q: Can this be used inside a fridge, such as in a motorhome to monitor the temperature in hot climates?**
A: I can't see why not, it's compact enough and has a magnet on the back. The only issue might be battery life, but it's probably worth a punt.

**Q: Does this item have Bluetooth and an app to view it on?**
A: Unfortunately not, these are entirely stand-alone so their details/readings cannot be viewed remotely.

**Q: Can i use this in my cigar humidor box? Humidity range between 65RH anf 75RH?**
A: I don’t see why not. The humidity range is specified as 10% to 99% RH, so as long as it will fit in the box there should be no problem. It’s not an application I’ve actually tried though.

### ⭐⭐⭐⭐ Basic but ok. May need to provide your own battery.
*by V***. on 15 July 2026*

Seems to work well, active as soon as battery is inserted & very simple/basic. Did have a momentary worry that it didn't work, but it turned out the battery provided was a dud.
