SELMA
STREET EVALUATING LASER METHANE ASSESSMENT
Combined methane leak detection solution: managed laser scanner plus precision gas detector
SELMA (Street Evaluating Laser Methane Assessment) is designed to search for gas leaks in urban environments. It is able to detect even a weak gas concentration moving at a speed of 60 km/h.

useful for
Underground
Gas Storage
Country Inspection
Transportation Gas Pipeline

SELMA advantages
Unrivaled detection accuracy
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.
How It Works?
The laboratory consists of two independent detectors.

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.

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.

SELMA Dome features
  • 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;
