KING JIM Ventilation Promoting CO2 Monitor - Black CD20-BK 1 unit

Catalog number: CD20-BK Features: ●This is a CO2 monitor that measures the CO2 concentration in an enclosed space and notifies you of the timing of ventilation with a numerical display, light color, and buzzer. ●The light around the main unit changes from green, orange, to red depending on the CO2 concentration, so you can intuitively know the CO2 concentration. ●It can be used to improve the environment in places where many people gather, such as classrooms in restaurants, cram schools, and schools, conference rooms, and living rooms. ●The photoacoustic (PAS) sensor accurately detects CO2. ●It is equipped with a high-precision photoacoustic (PAS) sensor and a calibration function. ●It accurately detects the carbon dioxide concentration in an enclosed space. ●It complies with the "Guidelines for the Selection of Carbon Dioxide Concentration Measuring Devices" issued by the Ministry of Economy, Trade and Industry. ●The three types of lights, green, orange, and red, allow you to intuitively know the CO2 concentration. ●In addition to the numerical display, the color of the light around the unit changes depending on the concentration of [CO2] every 3 minutes for 6 seconds, turning green (400-700ppm), orange (701-1000ppm), red (1001-2000ppm), or flashing red (2001-5000ppm), allowing you to intuitively know the air condition. ●It is easy to see the timing of ventilation even from a distance, so you can ventilate at the appropriate time.
