Features:
- Unrivalled sensitivity of 0.1 ppm
- Operates in automatic mode
- Effective for patrolling aboveground and underground gas pipelines
- Operates without loss of quality at a speed of up to 60 km/h
- Ideal for monitoring underground gas storages
- Can be mounted on any vehicle
Application/s
- Inspection of high and low pressure gas distribution networks
- Detects very small leakages
- Based on a pulsed IR laser system
- Detects leakages by utilising two independent laser detection systems: – Bumper laser for driveway leak inspection
- GPS registration comes as standard with the SELMA system
Overview:
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.
