Pergam Selma Duo - Gas Leak Detector with Carrying System

• Smartphone/tablet application makas gas detector operation simple and intuitive
• Above-ground gas detection with sensitivity in the ppm range
• Bluetooth data interfaces for reporting export
• Extendable probes for all types of surfaces
• GPS positioning data to within 50 cm accuracy, even in highly developed areas
• Light weight in your backpack.

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.

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.
