CO & CO2 Meters

Triplett offers carbon monoxide and carbon dioxide meters that help people assure indoor air quality by measuring CO, CO2, humidity, temperature, and dew points. They are widely used in restaurants, schools, offices, exhibition malls, and many public places. All our CO detectors and CO2 meters feature status indicators that change to depict good, normal, and poor along with the change in CO2 concentration in the room. All our indoor air quality meters feature a sensor that incorporates NDIR (non-dispersive infrared) waveguide technology and has a built-in CO2 automatic baseline calibration for long-term drift compensation. These meters are equipped with audio-visual alarms that inform people about abnormal concentrations. Our CO & Co2 sensors are backed with 1 -year warranty.

Maintaining indoor air quality is important to ensure the safety of people. CO and CO2 are two common gases produced as a result of human activities and various processes. These gases can have a detrimental effect on human lives.
