E+E EE892 Data sheet
EE892
The E+E CO2 module EE892 is designed for OEM applications and for
demanding environment. A multiple point CO
ment procedure leads to excellent CO2 measurement accuracy over the
entire temperature working range; this is a must for process control and
outdoor applications.
The E+E dual wavelength NDIR CO
automatically for ageing effects. EE892 is highly insensitive to pollution
and offers outstanding long term stability.
With its small dimensions and electrical connection via contact pins and
pads, EE892 is the optimal choice for OEM devices such as wireless
transmitters, hand-helds or data loggers. The measured data, with a
range of up to 10000 ppm, is available on the E2 digital interface.
An optional kit facilitates easy configuration and adjustment of the module. The measurement interval can be set according to the application
requirements; by this the average current consumption can be reduced to less than 60 μA for battery-operated devices.
