  • Page 3: Introduction

    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.

  • Page 4: Hygrostick® And Quikstick Humidity Probe Options

    ® Hygrostick and Quikstick Humidity Probe Options The Hygromaster is used with a detachable humidity probe to measure relative humidity and ambient temperature. Two humidity probes are available, the Hygrostick and the Quikstick. The Hygrostick is optimized for measuring humidity in the 30-100 %rh range and may be used with Protimeter humidity sleeves for measuring the equilibrium relative humidity of solid walls and floors.
