SG850-CO²
Conventional stand-alone carbon dioxide sensor for tertiary use. IP66
The SG850-CO² is a gas detection unit that in stand-alone mode, detects the presence of Carbon Dioxide. This sensor, through an infrared sensor, detects the presence of Carbon dioxide (CO2)
With this sensor it is possible to:
1) select alarm thresholds: 5%, 10%, 15% or 20%
2) select the positive safety of the relay
The sensor is managed by a microprocessor, which manages the execution of a self-diagnosis, and related automatic calibration, in order to always have the maximum detection accuracy. With this self-calibration, the probe adapts its detection in harsh and variable temperature environments, avoiding false alarms due to anomalous events.
Test: to perform a precise and self-certified test, use the TS1008 instrument, which also serves to carry out the annual check.
