Oldham OLCT 10 and OLC 10
Due to a housing issue with this range, the endurance test has not been passed as required by the ATEX certification. (Above 75°C with 90% Relative Humidity for four weeks). As a result, we can no longer guarantee the use of these detectors in an explosive atmosphere classified as ATEX Zone 2. For an ATEX approved alternative, click here.
We can deliver without ATEX markings if the detectors are not intended for use in an ATEX-classified area.
The OLCT 10 range can monitor toxic gases CO, NO, NO2, flammables or Freons. The OLC 10 is for flammable gases only.
An economical solution for continuous gas monitoring, ideal for garages, car parks, boiler rooms, charging rooms, refrigerant environments (freons) and hospitals. Rugged, small footprint, easy installation and operation.Compatible with Oldham’s MX15 controller or third party control panels. Detectors do not have a display.
