Relative humidity and temperature probe HITY 4000

wall-mountchannel-mountthin-film

The HITY is a humidity sensor and determines the relative humidity and temperature in gases. It is intended for installation in ventilation ducts or on the wall. The HITY works on the basis of an impedance measurement, it determines the humidity by means of the change in a hydrophilic polymer membrane built into the sensor. The measuring method does not require calibration, the sensor is extremely stable against chemicals and other aggressive substances, e.g. ozone, formaldehyde, axetone, isopropanol, methanol, toluene, hexane, etc. The sensor is insensitive to condensation and temperature changes are measured. The probe is insensitive to condensation, temperature changes are measured and compensated. Humidity changes are detected very quickly and output via the analogue interface. PROPERTIES: - Measurement of relative humidity between 20-95%. - Accuracy: up to 5%, most accurate at low humidity levels - Ambient and process temperature: 5 - 60°C (80° short term) - Pressure: 0-1 bar - Flow velocity: max. 20m/s - Saturation: <3% drift after 1000 hours at 100% humidity - Long-term drift: 0.1% per year in clean air - Protection class: IP65
