Ambient air checks become simpler when humidity and temperature are measured with one compact probe. Designed for GMH 3330 and GMH 3350 handheld meters, it supports universal portable use with a protective cap that combines mechanical protection with a stainless steel gauze filter for good air flow.
The probe covers 0.0 ... 100.0 % r.F. and -40.0 ... +100.0°C, with short-term temperature use up to +120°C at the probe head and tube. Accuracy is specified as ±2.5 % r.F. in the recommended range of 10 ... 90 % r.F. and ±0.5 °C at nominal temperature, giving dependable values for routine field and ambient measurement tasks.
Electronics integrated into the handle process measured values and store sensor data such as measuring range and calibration.
For demanding surroundings, the -POR option adds a plastic porous filter for use in dusty environments, powder paints and granulates.
The probe uses a capacitive polymer humidity sensor for air humidity measurement across the specified r.F. range.
A DIN class AA Pt1000 sensor records temperature.
The standard version uses a stainless steel gauze filter. The -POR version uses a plastic porous filter for dusty environments, powder paints and granulates.
The handle contains a circuit board for measured value processing and sensor data storage.
The probe is fitted with a shielded PVC connection cable and a molded 6-pin Mini-DIN plug with locking mechanism.
