ROTRONIC Temperature and Humidity Probe - HC2A-S

ROTRONIC Temperature and Humidity ProbeHC2A-S Description:
The HC2A-S is a fully featured high-precision temperature and humidity sensor probe produced by ROTRONIC AG, Switzerland, and serves as the foundation of the product line. It measures humidity, temperature, and calculates dew point and frost point.
The HC2A-S high-precision temperature and humidity sensor probe is widely used in HVAC, food, building equipment, papermaking, textile, pharmaceutical, and other industries.
The HC2A-S high-precision digital probe stores calibration data in the probe's internal memory. Measurement accuracy depends only on the probe. Compatible devices such as the HP32 portable hygrometer, HF5 or HF8 transmitters, and HL-NT3-D temperature and humidity data loggers read the probe's digital signal for monitoring, display, or transmitter output. Therefore, the digital probe features 100% field interchangeability, facilitating on-site probe replacement and maintenance.
