SERIES RHP HUMIDITY AND TEMPERATURE TRANSMITTER.

Description

Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES RHP HUMIDITY AND TEMPERATURE TRANSMITTER.
    The Series RHP Humidity/Temperature Transmitter combines the voltage or current humidity transmitter output with a passive temperature thermistor or RTD output. The polymer capacitance humidity sensor is not affected by condensation, fog, high humidity, or contaminants. The humidity sensors are available with 2% or 3% accuracies. Duct mounted transmitters are available with an optional two-line alphanumeric LCD display. The Series RHP is available with interchangeable filter options as well as replaceable sensors.
