Relative Humidity and Temperature Probe Relative Humidity and Temperature Probe RHT75 developed and manufactured by MicroStep-MIS, is designed for measuring air relative humidity and air temperature. RHT75 is a plug-in probe and a separate fast response temperature probe for meteorological and environmental applications, and any applications with continuous data monitoring. The high-quality sensor module for measuring humidity is 100% user-exchangeable without readjustment and offers many advantages. Performance Relative Humidity Measurement Measurement range Short term hysteresis Temperature dependence better than ±2 % over −20 °C to +60 °C Typical long-term stability ±1.0 % per year Calibration traceability Temperature Measurement Measurement range 100 % interchangeable Digital and analog interface Humidity sensor 0 to 100 % RH Accuracy typical ±2 % RH Long-term stability < 1 % RH/year Optional passive thermometer General Operating temp. range Storage temp. range Cable type low-temperature cable Housing material Housing classification Sensor protection sintered HD-polyethylene (optional sintered PTFE) Filter material porosity EMC compliance Inputs and Outputs Communication standard • SDI-12 V1.3 (responds to a subset of commands) • serial port • analogue output Output resolution Measurement period Supply voltage Optional PT100 Thermometer Accuracy classes Operating temp. range Recommended current depends on Data Logger Measurement period depends on Data Logger
