Introduction

The GE Protimeter 

Hygromaster

 is a handheld hygrometer with data logging capability. Spot 

measurements of relative humidity, dew point, mixing ratio and ambient temperature are shown 
on a split display at the touch of a button. Surface temperature can also be measured using an 

optional surface temperature sensor.

When used as a data logger, the instrument is set to record measurements as required and is left 
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 for quick and simple analysis.
