Capacitive Humidity and Temperature Probes for Squirrel Data Loggers

For applications requiring both temperature and humidity monitoring, e.g. museums, art galleries, weather stations, electronic enclosures, computer rooms, incubators, provers, cold stores.

Squirrel input required: V/C input type

Type VH-G-Z3-O

VH Humidity Probe
Construction Robust ABS housing with dust and pollution protection
Dimensions (mm) L 240, Handle Dia. 24, Body Dia. 18.5.
Lead 3m supplied
Lead options up to 100m
Humidity Sensor Vaisala HUMICAP™
Operating range 0 to 100% Relative Humidity
Accuracy (20°C) ± 1% RH against factory reference
± 2% RH against field references (0-90% rh)
± 3% RH against field references (90 to 100% rh)
Temperature Sensor U (Thermistor)
Temperature Range -40 to 60°C
Response Time 15s (membrane filter fitted. Start -up <1s)
Stability High under all conditions. Negligible hysteresis

Type RH-G-Z2-O

RH Humidity Probe
Construction Polycarbonate housing with dust and pollution protection
Dimensions (mm) L 165, Dia 15mm
Lead 2m supplied
Lead options (with amplifier) 5m to 100m
Humidity Sensor Rotronic HYGROMER™
Operating range 0 to 100% Relative Humidity
Accuracy (20°C) ± 1.5% RH
Temperature Sensor Pt100 1/3DIN
Temperature Range -40 to 85°C
Response Time < 0.7s (start-up 3s)
Stability < 1% RH/year
Note: The probe requires 2 V/C inputs on the datalogger. A built-in amplifier converts the inbuilt temperature sensor and humidity sensor to individual voltage outputs. The probe is powered from the logger.
