The ACI Relative Humidity Remote Probe utilizes a thermoset polymer capacitive sensing element with a hydrophobic filter to deliver a proportional relative humidity analog output The remote probe wiring harness comes in lengths of 3, 6, 10, or 20 feet to provide mounting flexibility for your remote sensing applications

Single point field calibration can be done on the humidity transmitter, by using the increment and decrement dip switches

Each toggle of the increment and decrement switches will allow for a ±0.5% RH increase or decrease

Calibration of the RH transmitters electronics can also be done using both the Zero and Span potentiometers depending on whether it is a current or voltage output device

All models feature conformally coated circuit boards to improve the reliability of the product in both high moisture and mildly corrosive atmospheres

A vinyl cap is provided to place over the sintered filter in wash down applications to protect the sensing element from getting moisture sprayed directly on the sensor

Three point NIST Calibration Certificates are available.
