SR-LD 800/200 Remote Laser Gas Detectors

Detect gas leaks over a distance of up to 200 metres

The new SR-LD 800 and SR-LD 200 remote laser gas detectors from SEWERIN enhance safety and efficiency in a variety of applications, such as inspecting a house’s connections from outside of the property’s boundary or checking gas pipes located under bridges. Additionally, all operational components at biogas plant can be easily inspected for leaks. Thanks to these devices’ remote detection technology, the tightness of the tank’s membrane connection can be inspected without the hazard and hassle of climbing ladders.

Thanks to the high resolution of the instruments’ measurement laser, these devices achieve exceptionally high sensitivity. The SR-LD 800 and SR-LD 200 are designed to detect methane gas and are both unaffected by cross-interference from other gases due to the use of TDLAS (Tunable Diode Laser Absorption Spectroscopy), a high resolution, non-dispersive spectrometric technique.

The SR-LDs efficiently detect methane gas even over long distances of up to 200 metres. A laser beam emitted by the detector is reflected of a surface. If methane is present along the measurement path, it will absorb the laser beam’s signal. The device calculates methane concentration based on signal attenuation. The devices adjust the zero-point automatically as the distance changes, ensuring reliable detection.

Both remote laser detectors are very compact, lightweight and user-friendly. They can be fully charged in just 2 ½ hours and are always ready for use thanks to the spare rechargeable batteries provided. The automatic adjustment of the measuring lasers is performed conveniently and efficiently within the carrying case.

How to reliably detect gas leaks over a distance of up to 200 metres

SEWERIN’s new SR-LD 800 and SR-LD 200 remote laser gas detectors significantly improve safety and efficiency in a variety of applications, such as checking a house’s connections from outside of the property’s boundary, monitoring gas pipes located under bridges, or inspecting every operational component at a biogas plant for leaks. Thanks to these devices’ remote detection technology, the tightness of a tank’s membrane connection can be scrutinised thoroughly without the hazard and hassle of climbing ladders to enter the tank.

These cutting-edge instruments achieve exceptionally high sensitivity because of the high resolution of their measurement laser. SEWERIN developed the SR-LD 800 and SR-LD 200 to detect methane gas unaffected by cross-interference from other gases thanks to the use of TDLAS (Tunable Diode Laser Absorption Spectroscopy), a high resolution, non-dispersive spectrometric technology.

The SR-LDs reliably detect methane gas over long distances of up to 200 metres. A laser beam is emitted by the detector and reflected on the pipe or tank’s surface. If there is methane present in the measurement path, the laser beam’s signal with be absorbed and therefore depleted. Methane concentration is measured based on how much the signal is weakened by the gas. The SR-LD 800 and SR-LD 200 both adjust their zero-point automatically to account for changes in distance, ensuring reliable and precise detection results.

Both of the remote laser detectors are extremely compact, lightweight and easy to use. They are fully charged within 2 ½ hours and are always ready for action thanks to the spare rechargeable batteries provided. The measuring lasers are adjusted automatically, conveniently and efficiently within the instrument’s carrying case.
