Proven Technology

Used in highly sensitive areas to detect low gas concentration levels to activate alarms when specific hazardous concentration levels are exceeded.

Thousands of Spectrex Series 200 open path gas detection units are installed on offshore platforms, FPSO’s, refineries, chemical manufacturers and other applications operated by leading global oil and chemical companies.

Cost Effective

A single system can monitor line-of-sight up to 460 ft. (140 m). The low cost of ownership, low installation costs, and minimal maintenance requirements further contribute to cost savings.

Robust Design

Specifically engineered to perform in harsh installations such as high-velocity airflows, humidity, and corrosive gases.

Fast Response

Adjustable light source flash rate gives high sensitivity and fast detection time. Also prevents detector from going into obscuration when a large cloud of gas passes through the beam.

Low Maintenance

High reliability, simple installation, easy alignment, and minimal maintenance.

Proven Technology

Used in highly sensitive areas to detect low toxic gas (H2S, NH3, Benzene, Xylene, Toluene, Carbon Disulfide) concentration levels to activate alarms when specific hazardous concentration levels are exceeded. System is trusted by leading chemical corporations for ensuring facility safety.

Fast Response

Adjustable light source flash rate gives high sensitivity and fast detection time.

Cost Effective

A single system can monitor line-of-sight up to 165 feet (50 m). Low installation costs and minimal maintenance requirements contribute to cost savings.

Robust Design

Specifically engineered to perform in harsh installations such as high-velocity airflows, humidity, and corrosive gases.

Low Maintenance

High reliability, simple installation, easy alignment, and minimal maintenance.

Standard Interface Options
