ECO 420 – Compact CO₂ monitor with alarm (formerly G 1910)

Category: Tags: , , ,

Description

Compact CO2 monitor with alarm for many applications in air quality monitoring, green houses, energy management and for research and education.

The CO2 is measured with a high-class non-dispersive infrared (NDIR) sensor via opening at instruments head.

Simultaneous display of time weighted average exposure over 8 hours (TWA) or 15 minutes (STEL).

CO2 – Dangerous at concentration > 3%
The ECO420 is an ideal measuring warning instrument for moderate but non-dangerous levels – it is no replacement for personal safety equipment to be used in areas with potentially dangerous atmosphere.

ATTENTION:
Never enter potentially dangerous areas where CO2 may exceed 3% or 30000 ppm CO2 without additional personal safety equipment!

Display
Thanks to the backlight, the three-line LCD display offers ergonomic wide-angle visibility – by day and by night.
The HOLD function enables the display values to be frozen.

Power supply
2 powerful AA NiMH rechargeable batteries, the energy-saving design and the configurable automatic switch-off function ensure long operation.
Configurable LCD backlight for further energy-saving options.
