  • ZG09 with a Dual Beam NDIR technology for making precision measurements in a wide range of applications is an affordable CO2 sensing solution for OEMs. The new small size module allows OEMs to integrate into smaller enclosures and equipment. ZG09 is ideal for the field where accurate CO2 levels need to be measured and controlled for indoor air quality, green house and energy-saving applications.
    general intro

    Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.
