Senseca ECO 420-02 Carbon dioxide measuring device 0 - 10000 ppm

Compact CO2 monitor with alarm for various applications in air quality monitoring, greenhouses, energy management, as well as in research and education. The ECO 420-02 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 potentially hazardous atmospheres. CO2 is measured using a high-quality non-dispersive infrared sensor (NDIR) through an opening at the device head. The simultaneous display of time-weighted average exposure is shown over 8 hours (TWA) or 15 minutes (STEL).

Applications include CO2 monitoring for professions exposed to increased levels: CO2 dosimeter over 8 hours average TWA. The device is highly portable with a belt clip and carrying strap and has a battery life of 24 hours. Air hygiene monitoring is conducted with two adjustable alarm thresholds; the first can be used as a ventilation alarm. In case of an alarm, the device beeps and flashes. For forced ventilation, the beeping can be silenced for 5 minutes at the push of a button. Continuous operation with a USB cable is possible.

The device serves as a traceable reference device to verify the usability and functionality of simpler CO2 monitors. The three-line LCD display offers ergonomic wide-angle visibility thanks to the backlighting – both day and night. The HOLD function allows the display values to be frozen.

Power is supplied by two powerful AA NiMH batteries. The energy-saving design and configurable automatic shut-off ensure long operation. The LCD backlighting is configurable to provide additional energy-saving options.

Warning: Never enter potentially hazardous areas where the CO2 concentration may exceed 3% or 30,000 ppm CO2 without additional personal protective equipment.
