GE Protimeter Moisture Meters

Protimeter HygroMaster Hygrometer

Versatile hygrometer that measures humidity, air temperature and dewpoint
The Protimeter HygroMaster is an easy to use hygrometer with built in data logging capability. The HygroMaster is a hand-held instrument for taking spot measurements and for logging humidity and temperature values. Quick measurements of relative humidity, dew point, mixing ratio (grains per pound/parts per million by weight) and ambient temperature are shown on a split display at the touch of a button. Surface temperature measurements can also be measured with an optional surface temperature sensor, making this instrument especially suitable for condensation risk assessment and diagnosis.

There are many applications where moisture and temperature trend analysis is required to gain a full understanding of a situation. The HygroMaster has a data-logging mode to meet this requirement. The user sets the instrument to record measurements as required and leaves it in place for the required period of time. The memory contents are then downloaded to a PC using optional software where the logged measurements are displayed in tabular and graphical form.

Two types of humidity probes are offered for use with the HygroMaster, the Hygrostick (POL750) and the HumiStick(POL7750-2). The HygroStick in optimized for measuring humidity in the 30-100% rh range and may be used with Protimeter humidity sleeves that are used when measuring the equilibrium relative humidity of solid walls and floors. The HumiStick is a fast responding sensor with a range of 1-100% rh making it more suitable for general air quality applications, including outputs from dehumidifiers and HVAC systems.
