Miniature CO2 modules with digital interface

EE893 and EE892 operate on the dual wavelength NDIR principle, which stands for outstanding long term stability even in demanding environment.

A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range.

With their low power consumption, miniature size and electrical connection via pluggable connector strips and edge card connector, EE893 and EE892 are the optimal plug-in modules for battery operated devices. They can be configured and adjusted by the user to match the requirements of most OEM applications.
