Product Details

The SERIES RHP Temperature and Humidity Transmitter combine the voltage or current humidity transmitter output with a passive temperature thermistor or RTD output. Featuring polymer capacitance humidity sensors, models are available in 2%, 3% or 5% accuracies. Duct mounted transmitters are available with an optional two-line alpha numeric LCD display.
For models with resistive thermistors or RTD outputs, please find temperature to resistance lookup tables.

Application Note:
For duct mount installations, the sintered filter option should be ordered for applications where the humidity transmitter is mounted in the supply air duct after the fan and cooling coils.

Features:
• 2%, 3%, or 5% accuracy models
• Optional LCD display on duct mount models
• Radiation shield option for outdoor installation in direct sunlight

Approvals:
• CE Approval

Applications:
• Air economizers
• Outdoor temperature and relative humidity reference
• Pool room humidity monitoring
