the sh300 series is a module for environmental testing chambers, with high-end humidity sensors and accurate temperature sensors, to meet the specific requirements of environmental testing chambers.
The SH300 Series RH/T module is designed for climate and drying chambers, offering precise relative humidity and temperature measurements. It features a 4-20mA output for humidity and a passive 3-wire temperature output. The module supports field calibration via push buttons and is compatible with OEM installations.
The module operates on 10–35V DC or 10–28V AC, with a working temperature range of -40 to 60°C. It includes a stainless steel grid filter and is designed for EMC compliance with EN61000-4-3 and FCC Class B standards.
