The HDR200 Series offers professional-grade humidity and dew point measurement for demanding industrial applications including compressed air systems, industrial dryers, environmental chambers, and high-temperature processes. Featuring NIST-traceable calibration and all-stainless steel construction, these transmitters deliver exceptional accuracy across extreme operating conditions.

Key technical specifications include dew point measurement capability from -60°C to +100°C with ±1.0°C accuracy from 40°C to -20°C, and relative humidity measurement from 0-95% (non-condensing) with ±1.0% accuracy at 25°C. The probe operates from 0°C to 200°C while electronics operate from 0°C to 85°C, with a pressure rating of 750 psi for compressed air applications.

The transmitter features dual output options: 4-20mA loop-powered or RS232 digital communication. The 2x8 LCD display provides 0.1% RH / 0.1°C resolution with user-selectable measurement modes (dew point/RH, °C/°F). Industrial-grade construction includes stainless steel probe, filter guard, and ½" NPT fitting with high-temperature cable rated for extreme environments. Available in remote transmitter and wall-mount configurations with optional M12 connector for enhanced connectivity.
