OLCT 20 Fixed Gas Detector
Indoor and Outdoor Gas Detection for Flammable, Toxic Gases and Oxygen Measurements.
SKU
OLCT20
The OLC(T) 20 Series of gas detectors are designed for indoor or outdoor facility monitoring and other applications to accommodate your gas detection requirements at a reasonable price.
OLC(T) 20 Detector
The new generation of OLC 20 combustible sensors are unaffected by poisons. The units provide extremely quick response times and complete reliability. They can be fitted on a housing with a M25 or 3/4" NPT thread.
The stainless steel detector provides protection and resistance to corrosive agents. Classified IP 66, they are resistant to dust and water ingress. The pre-calibrated sensors of the OLCT 20 can be disconnected by turning the head of the unit. These “smart” sensors can be calibrated on a work bench, outside hazardous areas.
