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 HF5/8, PF4/5 transmitter or HP32 and HP23 this probe is the first selection for many applications. Versatile Humidity Probe HC2A-S and HC2A-S3 The HC2A-S/-S3 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/-S3: Both humidity sensors are used for HVAC, food industry building services equipment, paper, textile and pharmaceutical industries. The HC2A-S3 version with its white body is additionally used for meteorology. Robust Humidity Probe HC2A-SM The HC2A-SM is the robust probe from Rotronic for harsh environments and adds to the wide product portfolio. It also covers humidity and temperature measurement and dew/frost point calculation. Applications for the Humidity Sensor HC2A-SM: Food, paper, textile, pharmaceutical and cosmetic industries
