HC2A-S Humidity Probe
Most versatile probe from ROTRONIC and forms the basis of the product portfolio, offering ±0.8 %rh and ±0.1 K accuracy
The standard Rotronic Humidity and Temperature probes can be used in application with temperature from -50…100°C / 0…100 % RH. With an outstanding accuracy ± 0.8% RH ±0.1°C. For calibration the probes can be replaced without almost any downtime. Together with a Rotronic HF5, PF4/5 transmitter or HP32 and HP23 this probe is the first selection for many applications. Versatile Humidity Probe HC2A-S The HC2A-S are the most sold versatile probes from Rotronic and form the basis of the product portfolio. They measure humidity and temperature and calculate the dew/frost point. Applications for the Humidity Sensors HC2A-S Both humidity sensors are used for HVAC, food industry building services equipment, paper, textile and pharmaceutical industries.
