The Protimeter Hygromaster L is a “lighter” version of the Hygromaster 2, but with the same great performance in accuracy and fast response! With a simple user interface and multi-function capability.

The Hygromaster L measures ambient humidity and temperature, dewpoint and specific humidity. It also incorporates a replaceable humidity and temperature sensor. This meter is ideal for flood damage restoration, building survey, concrete and concrete floor (in situ) moisture measurement.
