ACI A/RH1-D : Duct Relative Humidity Sensor, 1% Accuracy, RH Outputs: 0-5, 0-10 VDC & 4-20mA (Default), Plastic Duct Enclosure (Euro), Made in USA

Maintaining optimal humidity levels in your building's ductwork is essential for several reasons. It can improve indoor air quality, increase occupant comfort, and even enhance energy efficiency. Here's where duct humidity sensors come in.

ACI A/RH1-D Duct Relative Humidity Sensors are specifically designed to monitor and control humidity in air ducts. They offer:

  • High Accuracy: Measures humidity with ±1% accuracy, ensuring precise control.
  • Durability: Built with a weatherproof enclosure and a hydrophobic filter to resist moisture, dust, and dirt.
  • Versatility: Compatible with various AC or DC power sources and features selectable output signals (4-20mA, 0-5VDC, or 0-10VDC).
  • Easy Calibration: Field calibration using DIP switches eliminates the need for sensor replacement.

Applications:

  • Humidification/Dehumidification: Precisely control humidity levels for various applications.
  • HVAC Systems: Optimize energy efficiency and control ventilation in buildings with economizers.
  • Clean Rooms & Data Centers: Maintain critical humidity levels for sensitive equipment and processes.
  • Hospitals, Schools & Offices: Create a comfortable and healthy environment by controlling indoor air quality.

ACI A/RH1-D Duct Relative Humidity Sensors are a reliable and cost-effective solution for building automation, HVAC control, and various industrial applications.
