We Invent to Prevent.

Natural Gas Leak Detection & Power Line Inspection

Pergam China — is a subsidiary of Pergam-Suisse AG international manufacturing company with headquarters in Zurich. We invent equipment and provide services for natural gas (methane) leak detection.
2003
A device based on the method of remote laser spectroscopy was developed for helicopter-based diagnostics of main gasline linear parts.
2005
Pergam Technical Services incorporated for sales, service and support.
2006
We obtained the U.S. Authority's approval for flight inspection of main gaslines (we tested ALMA at the area of Rocky Mountain Oilfield Testing Center).

A remote vehicle-based methane detector was developed, which expanded the capabilities of SELMA mobile laboratory.
2007
International patents in the USA and Europe.
2009
Start of shipments to China, South Korea, Estonia, and other countries.
2010
Italian office was founded for promotion of proprietary developments on the European market.
2011
Production begins on updated SELMA Version; sensitivity increased 10 times (up to 0.1ppm)
2013
LMS fixed installation remote methane detector was developed for continuous gas content monitoring at gas transport system open processing areas.
2014
An intrinsically safe version of LMS was developed for shipment to South Korea (Korea Gas).
2015
First shipments of SELMA and helicopter-based remote detector to Australia and New Zealand.
2017
First fixed-wing sensor successfully installed and flown.
2018 — 2019
Full-scale production of methane detectors for use on UAV platforms.
2021
Highly sensitive gas leak detector backpack system for walking and vehicle surveys.
2022
Mathematical model of gas leaks quantification for TDLAS detectors.
2023
A wearable detector with voice control and augmented reality (AR) glasses has been successfully tested.

We've developed the ALMA G5 portable laser methane detector for UAVs and small aircraft.
2024
We've finished the software and updated the Pergam ALMA G5 interface.
Any Challenge. Any Platform. Any Facility.

Solutions for Gas Leak Detection
based on Tunable Diode Laser Absorption Spectroscopy (TDLAS)

Customized
Lightweight and compact laser detectors for remote methane leak detection.
Stationary laser methane detectors for round-the-clock scanning of areal facilities.
Gas leak detection by vehicle for use in urban areas. Laser detectors on roof and bumper mounts.
Aircraft laser detectors designed to monitor extended gas facilities.
A series of remote laser detectors for installation on unmanned aerial vehicles.
We develop customized equipment based on customer needs.
The remote laser detector measures methane concentration in the air. The laser beam (having the wavelength, which corresponds to methane absorption line) reflects from a topographic object (the ground, a wall, etc.), which is 150 m away from the device and returns into the receiving channel of the optical system. Concentration is measured along laser emission and is displayed in a relative value, i.e. ppmxm.
