COTK-4 Carbon Dioxide Indoor Air Quality IAQ Temperature Humidity Meter Tester CO2 Gas Detector
The industrial wall mount CO2 Sensor & Controller is designed for fast & accurate measurement of CO2 level, humidity, and temperatures of air, dew point, and wet CO2 bulb.
The meter is designed with a built-in relay, which can be connected to an Indoor Air Quality (IAQ) system to control the opening and closing of the system.
In addition, it has PC Link that can send gathered data directly to your PC for online logging and data analysis via the optional RS-232 interface and software (not included in the set).
Areas of Application:
Hospitals, Offices, Schools, Theaters, Indoor Sports Arenas, High Rise Buildings, Indoor Area Quality, Commercial Buildings, Residential Housing, Public Buildings, Demand Controlled Ventilation, Clean Rooms.
Poor indoor air quality in rooms can lead to fatigue, lack of concentration and illness (Sick Building Syndrome) due to a high concentration of CO2 level.
