SG850-O²

Conventional stand-alone oxygen sensor for tertiary use. IP66

The SG850-O² is a IP66 gas detection unit that in stand-alone mode, detects the presence of  Oxygen

This sensor, through an optical fluorescence sensor, detects the presence of Oxygen (O2)

With this sensor it is possible to:

1) select the alarm intervention for:  >oxygen excess or <deficiency

2) select the positive safety of the relay

The sensor is managed by a microprocessor which also 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.
