E+E EE893 Specifications

EE893
Digital CO2 Sensor Module for OEM Applications
The E+E CO2 module EE893 is designed for OEM applications and for demanding environment. A multiple point CO2 and tem­perature adjustment procedure leads to excellent CO ment accuracy over the entire temperature working range; this is a must for process control and outdoor applications.

sates automatically for ageing effects. EE893 is highly insensitive to pollution and offers outstanding long term stability.
With its small dimensions and electrical connection via contact pins and pads, EE893 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 10000ppm, 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.
