  • Temperature compensation
  • Very low temperature dependency
  • 4.75 to 7.5VDC supply


The E+E EE893 CO2 Module is designed for OEM applications and for demanding environments. A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range. The dual wavelength NDIR CO2 sensing procedure compensates automatically for ageing effects. The EE893 is highly insensitive to pollution and offers outstanding long term stability

With its small dimensions and electrical connection via contact pins and pads, the EE893 modules 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.

Applications for the EE893 CO2 Modules include:

  • Data loggers
  • Handhelds
  • Wireless transmitters
  • Building automation
  • Demand controlled ventilation
