The Telaire HumiTrac Humidity Transmitter is designed for building automation/HVAC and general purpose RH monitoring. All models incorporate a NIST traceable, field-replaceable sensor tip and a rugged capacitive sensing element capable of 0–100% RH measurement. Field-configurable output options (0–5V, 0–10V, 4–20mA) are selectable via slide switches.

The field-replaceable sensor module maintains ±2% RH accuracy and NIST traceability; calibration constants are stored in the sensor module memory. The HumiTrac features a rugged capacitive sensor with excellent response time, linearity, stability, and recovery to condensation. Integrated filter and conformal-coated module electronics ensure long life. Signal-conditioned temperature versions maintain specified RH accuracy across -40 to 60°C. Enclosures are rugged flame-retardant UL-94V ABS plastic, with duct and outdoor versions offering IP42 weather resistance. Applications include HVAC, energy management, enthalpy control, IAQ, clean rooms, museums, hospitals, refrigeration, and pharmaceutical.
