Review on ALLOSUN Digital Thermo-Hygrometer with Humidity Alarm & Long Probe: High-Quality Humidity Monitor and Dew-Point Meter by Dezz Watson

This is a product that I have needed for a while. My only wish is to have a louder alarm, although this may require a mains (rather than battery) powered device. The humidity measurements are surprisingly accurate for such a cheap device. I have repeatedly tested the unit using a digital hygrometer (>$100) which does the necessary double readings and wet and dry bulb calculations. As the name of this product would suggest, it also performs dual measurement, although not with the accuracy of a high-end instrument.
