CO210 Desk CO2 Meter
10478
CO210 is a Desktop Indoor Air Quality CO2 Monitor/Datalogger. Measurement ranges are 0 to 9,999 ppm (CO2), 14 to 140°F (-10 to 60°C) for Air Temperature and 0.1 to 99.9% for Relative Humidity. It features Minimum/Maximum CO2 value recall, Year/Month/Date/Time display, and an Automatic Baseline Calibration (minimum CO2 level over 7.5 days) or manual calibration in fresh air. Comes with AC adapter and user manual. CO2 meter against COVID The Extech CO210 CO2 air quality meter is highly suitable for the prevention of spreading the Coronavirus within your office or indoor workspace. The easily readable display shows you at which eleven ventilation of the room is required to prevent the virus from spreading by air. A preset alarm at a ppm level at your requirement will notify you if the max. ppm is reached in the room. Place the Extech CO210 CO2 meter on your desk to monitor the air quality in your workspace or office. 450 “ 800 PPM: The office space is well ventilated. 800 “ 1200 PPM: Bad ventilated, busy working space. Loss of concentration can start at this level, and the Coronavirus can be spread. Ventilation is required. 1200 “ 2000ppm: Unpleasant feeling, lack of concentration. Ventilation is obligated at this level or above.
