The HF5A series is a newly developed temperature and humidity transmitter. Compatible with Rotronic digital (HC2, HC2A, and RMS) probe series, suitable for temperature and humidity, single temperature, and differential pressure. HF5A can also provide all standard humidity parameter outputs. Our advanced digital probe integrates AirChip3000 technology, so the probe has high precision, depending on the selected probe. For humidity and temperature measurement, the HygroFlex5 Advanced Edition HF5A-21, HF5A-31, and HF5A-D1 transmitters combined with the HC2A-S probe provide excellent accuracy and advanced functionality, taking humidity and temperature measurement accuracy to a new level at 23 ° C, with humidity of ± 0.8% RH and temperature of ± 0.1 ° C. The output of HygroFlex5 includes current, voltage, and Modbus RTU via RS485.
