O2 SL – Plastic Oxygen Sensor

Typical applications include the measurement of Oxygen deficiency in confined spaces such as tunnels, mines or chemical plant or for the analysis of combustion gases in flues and chimney stacks.

The SL`s shock resistant, leak free design ensures lifetime reliability. High sensor to sensor repeatability and high tolerance to temperature and pressure transients also contribute to highly reliable performance. All SL oxygen sensors have lifetimes of 18 months.
