ACI A/RH3-20K-R : Room Relative Humidity Sensor, 3% Accuracy, RH Outputs: 0-5, 0-10 VDC & 4-20mA (Default), 20K Ohm Thermistor, Room (R) Infinity Enclosure (Beige), Made in USA

The ACI Relative Humidity with Thermistor Room Series utilizes a thermoset polymer capacitive sensing element with a factory fitted hydrophobic filter to improve its moisture resistance. The sensing elements multilayer construction also provides excellent resistance in applications where dust, dirt, oils and common environmental chemicals are found. The RH room sensors include on board DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Single point field calibration can be performed by using the increment and decrement calibration DIP switches to adjust your curve up or down in +/- 0.5% increments with each toggle of the corresponding switches. These enhancements provide increased flexibility and outstanding long-term reliability without the need to replace the sensors in the field.

Applications:

Humidification
Dehumidification
Monitoring Indoor Space Humidity
Clean Rooms
Hospitals
Process Control
Laboratories
Museums
Schools
Office Buildings
Data Centers
ESD (Anti-Static) Control
