E+E Elektronik EE871 User manual

The E+E CO2probe EE871 is designed for use in harsh, demanding applications. It incorporates the dual wavelength NDIR CO2
sensor, which compensates for ageing effects, is highly insensitive to pollution and stands for outstanding long term stability.
A multiple point CO2and temperature factory adjustment leads to excellent CO2measurement accuracy over the entire
temperature working range.
The measured data range of up to 10 000 ppm CO2is available on E2 digital interface.
For use in special applications do not hesitate to contact E+E Elektronik or a local distributor.
GENERAL
USER GUIDE
EE871 – CO2Sensing Probe for the EE240 Wireless Sensor Network
• The device shall not be exposed to extreme mechanical stress. The sensing head and mostly the sensing cell might not be
exposed to any mechanical stress.
Probe
Filter cap
CO2Sensing cell
Sensing head
• 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.
