  • Description


The OLCT 100 fixed detector has been designed for detection of combustible gases, toxic gases or oxygen.

Whatever your application, the detector OLCT 100 is the solution: catalytic, electrochemical, semiconductor, or poison control version. ATEX approved, these detectors are available in explosion safe or intrinsically safe versions. In addition to this the OLCT 100 offers an infrared sensor, which allows it to be used in more severe environmental conditions, where the presence of poisons could harm the use of a catalytic sensor.

The stainless steel version offers increased resistance to corrosive elements .This version is certified for use in zones 0 (gas) and 20 (dust), whereas all other versions of the OLCT 100 are certified for use in zones 1 (gas) and 21 (dust).
