Wall Mount CO2 Fixed Gas Monitor

Overview

Indoor Air Quality (IAQ) is measure of the quality of air in interiors; the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO₂concentration is an important factor in good indoor air quality.

The CO₂Wall Mount Monitor is a cost effective and reliable unit designed to detect the presence of carbon dioxide (CO₂) in the ambient air to protect people in confined spaces or simply to monitor the living and working environment. With the simple fact that more windows are often closed to avoid noise, dust or simply because people enjoy the comfort of living and working in an air conditioned office, this usually results in increased indoor concentrations of carbon dioxide when compared to the outdoor environment. High concentrations of CO₂in confined spaces is dangerous and may lead to a range of health problems ranging from headaches and fatigue to asphyxiation and death.

The CO₂Wall Mount Fixed Gas Detector is not limited to applications in wineries. The unit is also a cost effective solution for carbon dioxide monitoring at swimming pools, gymnasiums, offices and more.

Features

Wall Mount CO2 Fixed Gas Monitor Features:

Dual Beam NDIR (Non-Dispersive Infrared) technology is used to measure CO2 concentration up to 50,000 ppm (parts per million) and electrochemical technology to measure O2 concentration up to 30%.
With the SEU (Sensor Unit) and RDU (Remote Display Unit), it can connect up to 3 RDU for safety notices.
Large digital LCD display clearly indicates the ambient CO2, O2(optional) Concentration and Temperature.
Relay output can automatically control a fan to ventilate confined spaces.
Audible and Visual Alarm indications.
IP54 Water Proof Protection of SEU (Sensor Unit) except backside when installed on the wall.
