A nice meter for moisture and drybulb temperature
4.0
I purchased the RH390 to monitor drybulb temperature and dewpoint in our calibration lab. Overall, I'm happy with the unit as it's compact and provides the accuracy I'm looking for. The fact that it provides a dewpoint readout is great, as this is a more fundamental measure of moisture levels. One aspect of the meter I don't like so much is that it's hard to see the text in its display that signifies when the moisture measurement is reading as dewpoint. The text is really small. Having said that, this is something that I think I'll just get used to over time.
