RH300
Works great. I lost my Extech pocket model so this is a replacement for it. I like the feature for closing off the ports on the sensor tip. I tend to have the instrument in my truck or in a briefcase so this feature is welcomed. The larger display is much easier to read for me.

Cheap Meter works OK
This hand held device works OK, it will tell you RH and Dew point very well but the temperature is always 8 to 10 degrees lower than actural room temps.If you really need true reading, don’t purchase this one spend more cake and buy a better unit.

Good Psychrometer
This psychrometer is portable and easy to use. Their measurements are quite accurate, but take time to stabilize. The thermocouple connector is quite useful. This meter has multiple functions such as humidity, temperature, temperature difference and dewpoint.

view window easily scratches. RH/DP way off
Only used product twice in crawlspace. Casing is weak, view window easily scratches. RH/DP way off. Should come calibrated. Should include calibration canisters for calibration, instead there’s an addition charge for that item. I will be returning this product. I could see it may be useful to some industries, but not for contscko

These are the humidity meters that we use for work. We don’t use the measured dew point, instead we do our own calculations to determine it (I find that the measured dew point is off).This meter is very easy to use. Just make sure that you aren’t holding the meter too close to your face (otherwise your breath will skew the results).
