The OLC 10, OLC 10 TWIN and OLCT 10 EXPLO combustible gas detectors are detectors fitted with catalytic sensors and intended for use in boiler rooms and parking lots.
The OLCT 10 TOX gas detectors are 4-20mA transmitters equipped with electrochemical sensors and especially designed to detect toxic gases in commercial and light industrial applications (parking lots, boiler room, etc).
Different versions available
-OLC 10: combustible gas
-OLC 10 TWIN: combustible gas
-OLCT 10 EXPLO: combustible gas (transmitter version, 4-20 mA output)
-OLCT 10 TOX: toxic gas (transmitter version, 4-20 mA output)
