    CO2 sensorCO2 sensors for building air-conditioning control and indoor environment measurement

    Customers can expect highly accurate measurements, long-term stability, and maintenance-free operation.
    The sensors have a design life of 10 years and feature a high-performance air filter and a built-in surge protector circuit.
    Also available are special cases designed for easy installation on ducts.

    Compliant with “Guidelines for Selecting CO2 Measuring Instruments”*

    Challenges in building air-conditioning control and indoor environment measurement, and 萝莉影视’s strengths

    Challenges in building air-conditioning control and indoor environment measurement

    • Accurate measurements are necessary because age-related deterioration of buildings and environmental conditions such as humidity and temperature can cause measured values to fluctuate.
    • The Building Maintenance Act (officially the Act on Maintenance of Sanitation in Buildings)* sets out “Sanitation Maintenance Standards for Building Environments,” which define the requirements for maintaining buildings in terms of environmental sanitation. The standard for carbon dioxide content under the “Air Environment Regulation” section of the standards is 1,000 ppm or less.
    • Energy loss in air-conditioning due to settings predicated on drift (a property resulting in consistent error)
    • Calibrating CO2 sensors is difficult because they are installed in high places and other locations that are difficult to access, and calibration requires a reference gas.
    • *The Building Maintenance Act is a law concerning the maintenance of “specified buildings” used by many and unspecified people, and sets out environmental sanitation requirements for maintaining buildings.

    Strengths of 萝莉影视 CO2 sensors

    萝莉影视’s CO2 sensors use the dual-beam NDIR method for accurate measurements even at CO2 concentrations below 400 ppm, well within the Building Maintenance Act standard (1,000 ppm). Also, the model designed for installation in building air-conditioning ducts makes replacement easy.
    In addition, with our unique mechanism and algorithms, our sensors are self-calibrating when measured values start to stray, making them maintenance-free and stable over the long term, and thus saving energy.
