Description

Overview of the Street Evaluating Methane Laser Assessment – SELMA Bumper

The SELMA Bumper is a diagnostic gas detection tool for leaks in urban areas. The system detects gas leaks by simply driving down the street past the inspection area, even when maintaining a normal driving speed. With two independent laser detectors, the Selma detects leaks in front and at the side of the driving path.

The SELMA Bumper is highly sensitive and utilises a simple operation process and data assessment. It is also suitable for most vehicles.
