Setra's SRH family consists of wall mount, duct mount, and outside air units designed for HVAC/building automation and relative humidity monitoring. All models feature removable NIST traceable sensor tips, a durable capacitive sensor capable of 0–100% RH measurement, and field-replaceable tips that eliminate factory calibration and reduce downtime.

The SRH line offers accurate humidity with active or passive temperature sensing. Humidity transmitters with active temperature option have jumper-selectable Tspan ranges (40°C, 50°C, 60°C). Three accuracy levels: 2%, 3%, and 5% RH. The robust capacitive sensor paired with custom ASIC ensures reliable measurement, better contamination resistance, longer stability, and minimal drift. Enclosures: low profile wall mount, duct, and outside air models. Electronics warranty: 5 years; sensor module: 2 years. CE and RoHS compliant.
