Oldham OLCT 60 Gas Detector

  4-20 mA analog transmitter with display
  SIL2 capability for combustible gases
  Detects O2, combustible, toxic and refrigerant gases
  Corrosion resistant
  Designed for industrial applications
  Available with remote sensor head, flameproof or intrinsic safety versions
  Non-intrusive, one-man calibration
  New XP IR infrared sensor for combustible gases or CO2

Oldham are proud to introduce the OLCT 60, the latest generation of high quality gas detector. The OLCT 60 meets the needs of a wide variety of industrial applications.

There are several versions of the OLCT 60 available including XP or IS sensor (toxic or oxygen versions) and remote or on-board sensor.

The sensor to be installed remotely up to 15 meters (standard) using the OLCT 60AD version. This allows detection in inaccessible locations, or in Zone 0 in the case of the intrinsically safe (IS) version.

Rugged and resistant to corrosion, the OLCT 60 is made of 316L stainless steel. Pre-calibrated sensors can be disconnected by turning the head of the unit. These "smart" sensors can be calibrated outside hazardous areas.
