Page 6: Product Description
Product Description Operation Principle The EE872 is available in three versions (see also Fig. 5) EE872-M10...: The probe measures the CO concentration. The sensing module is heated by factory default setting to prevent condensation. The CO measurement value is available on the analogue output or on the digital interface. -

Page 8: Installation
Installation Best measurement performance is achieved when the entire probe is located inside the environment to be monitored. This is the case, for example, when the EE872 is fixed onto a wall with the mounting clip HA010227 (not included in the scope of supply, see data sheet “Accessories”), or freely hangs from the ceiling on the connection cable. -

Page 12: Changing The Filter Cap
Changing the Filter Cap In a dusty, polluted environment it might be necessary to replace the filter cap once in a while. In most of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the CO measurement also indicates a clogged filter cap. -
