Product Information

Overview

Introducing the OLC(T) 50, a new generation of high quality gas detectors designed for manufacturers, refineries and other industries to accommodate your gas detection requirements at a great price.

OLC(T) 50 Detector
The enclosure, which is made of alloy AS7 606 is coated with polyester epoxy paint (stainless-steel is also an option), and is rugged and resistant to corrosive agents. The OLC(T) 50 detectors are practical and easy to use. The combustible gas sensors are insensitive to poisons, offer quick response times and provide accurate gas measurement.

OLC(T) 50D Detector
Based on the OLC(T) 50 detector-transmitter, the OLC(T) 50D allows the detector unit to be used in remote mode. The detector is equipped with a 15 meter long cable (standard) and a packing gland for direct connection for detection in difficult locations.

New Generation: New Advantages
The detector units, which are made of 316L stainless steel, are durable and resistant to harsh environmental elements. Certified IP 66, OLC 50 and OLCT 50 Series are tightly sealed to avoid contamination from dust and liquid splashes. The pre-calibrated sensors of the OLCT 50 and OLCT 50D can be disconnected by simply turning the head of the unit. The “smart” sensors can be calibrated outside hazardous areas on a bench.
