Senseca ECO 420-20 Carbon dioxide detector 0 - 19999 ppm
Compact CO2 monitor with alarm for many applications in air quality monitoring, in greenhouses, in energy management and in research and teaching. The ECO 420-20 is an ideal measuring and warning device for moderate but non-hazardous concentrations - it is not a substitute for personal protective equipment that must be used in areas with a potentially hazardous atmosphere. The CO2 is measured by a high-quality non-dispersive infrared sensor (NDIR) via an opening on the device head. Simultaneous indication of the time-weighted average exposure over 8 hours (TWA) or 15 minutes (STEL).ApplicationsMonitoring CO2 for occupations exposed to increased exposure: CO2 dosemeter over 8 hours average TWA. Very mobile because of belt clip and carrying strap and 24 h battery life!Air hygiene monitoring with two adjustable alarm thresholds. The first can be used as an alarm for ventilation; the device beeps and flashes in case of an alarm. For forced ventilation the beep can be suppressed for 5 minutes by pressing a button. Continuous operation possible with USB cableTraceable reference device for checking the usability and function of simpler CO2 monitorsDisplayThe three-line LCD display provides ergonomic wide-angle visibility thanks to the backlight â during the day and at nightThe HOLD function makes it possible to freeze the displayed valuesPower Supply2 powerful AA-NiMH-batteries, the power-saving design and the configurable automatic switch-off provide for a long operationConfigurable LCD-background lighting for other power saving possibilitiesCautionNever enter potentially hazardous areas where the CO2 concentration can exceed 3% or 30000 ppm CO2 without additional personal protective equipment!This text is machine translated.
