Relative Humidity Sensor Replacement

The Replaceable Sensor Tip for Easy Calibration SRH offers the industry’s easiest replaceable sensor tip. Removing it requires no special training and can be easily replaced by the end user.

Overview

The Replaceable Sensor Tip for Easy Calibration SRH offers the industry’s easiest replaceable sensor tip. Removing it requires no special training and can be easily replaced by the end user. No calibration is needed because each sensor module is factory calibrated before shipping, reducing downtime during service intervals. The SRH outdoor humidity sensor offers optional active temperature with choice of 4 to 20 mA or user-selectable 0 to 5 and 0 to 10 VDC output and passive temperature with choice of thermistor or RDT output. The sensor is housed in a polycarbonate 94 V-0, NEMA 4 enclosure making it suitable for harsh environments. The SRH outdoor air sensor gives the user the choice of 2%, 3% and 5% RH accuracy to meet the requirements of typical HVAC applications. It features a removable sensor tip, NIST traceability and a durable capacitive sensor capable of a 0 to 99% full scale RH measurement and recovery from 100% saturation.
