Review on Mengshen Temperature Multi Function Thermometer Hygrometer by Michael Cleveland

If you need a similar product, this is a good choice. It works as it should and gives the impression of a quality instrument. When tested with my mechanical humidity and temperature gauges (of known high accuracy) this gauge was accurate on temperature readings and within 1% on humidity readings (very acceptable performance). The only caveat is that you must wait at least a minute for the moisture reading to stabilize before you get the most accurate reading. I can't comment on the accuracy of the wet/dry bulb.
