Oldham Simtronics OLCT 60 Fixed Gas Detector
Bulk Orders
The generation of high quality gas detectors designed for the detection of flammable, toxic gases or oxygen.
The OLCT 60 Series is available in several versions:
- Explosion-proof XP or intrinsically safe IS sensor (combustible, toxic or oxygen versions).
- Remote or on-board sensor. The OLCT 60 can be remotely mounted, allowing detection in inaccessible locations or in Zone 0 or 20 in the case of the intrinsically safe (IS) version.
The OLCT 60 is equipped with a local display and non-intrusive access to a safe menu. In hazardous areas, calibration can be done without the need of a hot work permit.
The detector units are made of 316L stainless steel, and are rugged and resistant to corrosion.
Certified IP66, the OLCT 60 is sealed against dust and splash water. The versatile instrument is the ideal solution for gas detection covering all industrial needs for a wide variety of applications.
Features
- Pre-calibrated sensors
- Non-intrusive calibration
- Infrared Version
Infrared sensor available
An infrared sensor is already available for CO2, SF6 and refrigerant gases detection.
