Model:AQDTF

Description

The Indoor Air Quality Sensor uses an advanced MEMS metal oxide semiconductor sensor to detect poor air quality. The sensor reacts quickly to detect a broad range of VOCs such as smoke, cooking odors, bio-effluence, outdoor pollutants and from human activities. The sensor captures all VOC emissions that are completely invisible to CO2 sensors. A weatherproof Polycarbonate enclosure is provided for ease of installation.

Features

  • True Air Quality Monitor
  • Microprocessor based controller
  • Linear and stepped analog output
  • Optional relay output
  • Optional temperature sensor
  • LCD Display
