Pergam Selma Dome - Remote Laser Detector
360° leak detection: SELMA Dome is a remote laser detector on a rotary platform. It is mounted on the vehicle top to monitor gas leaks within a radius of 150 meters.
- Effective both during parking and while driving
- Scanning modes: directional (manual), circular
- Methane detection through window glass
- Laser radiation is safe for humans
- No special person required; a driver/operator is enough
- Built-in GPS receiver for accurate leak location
Successful combination
SELMA vehicle-based laboratory comprises two methane detectors: a remote laser scanner on the roof which detects leaks up to 150 meters away, and a bleeding high-sensitivity detector with a bumper air intake which detects gas directly in front of the vehicle.
High-speed survey
SELMA vehicle-based complex can survey up to 150 kilometers of urban infrastructure per one working day. This is ten times more than a foot patrol personnel could walk.
Quiet and safe
Scanning laser of the remote detector meets all safety standards and is absolutely harmless to humans and animals. A video camera without a laser target finder is used to aim at the living premises which will not disturb residents at all.
SELMA Dome is a laser remote detector mounted on the vehicle top and scanning the surrounding area for methane leaks within a radius of 150 meters.
SELMA Duo - is an unical high sensitive vehicle sensor and handheld portable advanced leak detector capable of detecting methane and ethane without false alarming on other gases. This allows you to detect a leak while driving a car and accurately locate it with extendable probe. It is also an effective tool for Method 21 emissions leak detection
Detectors can be used both in combination (recommended), and separately.
