Teledyne Oldham OLCT 60 Fixed Gas Detector

SKU
Oldham-OLCT-60

Teledyne Oldham OLCT 60 Fixed Gas Detector

The Teledyne Oldham OLCT 60 is the latest generation of high-quality gas detector, meeting the needs of a wide variety of industrial applications.

OLCT 60 Key Features:

  • 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 

There are several versions of the OLCT 60 available including XP or IS sensor (toxic or oxygen versions) and remote or onboard sensor. The sensor can be installed remotely up to 15 meters (standard) using the OLCT 60AD version. This allows for 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.
