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
