The E+E CO
2
probe EE871 is designed for use in harsh, demanding applications. It incorporates the dual wavelength NDIR CO
2
sensor, which compensates for ageing effects, is highly insensitive to pollution and stands for outstanding long term stability.
A multiple point CO
2
and temperature factory adjustment leads to excellent CO
2
measurement accuracy over the entire
temperature working range.
The measured data range of up to 10 000 ppm CO
2
is available on E2 digital interface.
For use in special applications do not hesitate to contact E+E Elektronik or a local distributor.

•
The device must be operated with the filter cap on at all times. Do not touch the sensing cell or electronics inside the sensing
head.
•
A long response time indicates a dirty filter cap, as it might happen in polluted applications. Do not attempt to clean the filter
cap; it would only cause its clogging. Replace the filter cap by an E+E original one, order no. HA010116.
•
While replacing the filter cap take utmost care to not touch the sensing cell and the electronics.
•
This device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure
could cause injury to human beings.
