Phoenix Restoration has added the HM40 ThermoHygrometer to its line of precision humidity meters, a more advanced version of the HMI-41. Specifically, the meter displays temperature, relative humidity percentage, dew point, wet bulb temperature, grains per pound and BTUs per pound.

 

It’s a compact, portable and convenient tool to use when fast, accurate and reliable measurements are needed and it offers large graphic displays and push buttons for ease of use.
