Safeguarding the working environment

March 2005 Analytical Instrumentation & Environmental Monitoring

It is essential to prevent the risk of asphyxia, poisoning or explosion, caused by the presence of gas, to ensure a safe working environment. The OLC 20 series are catalytic cell type detectors, intended for the detection of combustible and toxic gas, as well as oxygen. These detectors are available in explosion proof protection mode or intrinsic safety protection mode.

The cell units are made of 316L stainless steel, to provide robustness and resistance to corrosive agents. Resistant to dust and water ingress, the new generation of explosometric cell units is unaffected by poisons and exhibit quick and reliable response times.

Based on the OLC 20 cell unit, the OLCT 20D detector is equipped with a 15 m long cable (standard version) and stuffing gland for direct connection to a datalogger. A high temperature version allows operation at 200°C. The OLCT 20 cell units, which are fitted with pre-calibrated cells (explosometric, toxic or oxygen type), are classified as flameproof according to the user's needs, or the gases to be detected.

Accessories include a tool kit, a gas input device, a gas circulation head for CO, H2S, O2, and explosive gases. There is an anti-splash device, a remote gas injection device, PTFE protected filter, gas collectors, Pitot tube and a remote fastening device.
