Natural Gas Leak Detection & Power Line Inspection

Pergam Italy S.R.L. — is a part of Pergam Group international manufacturing company. 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 (USA) 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.

2020

Released an updated version of the remote vehicle-based methane detector SELMA Dome.

2021

Highly sensitive gas portsble sniffer SELMA Duo for walking and vehicle surveys.

2022

Mathematical model of gas leaks quantification for TDLAS detectors.

Opened a branch office in China.

2023

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.

Handheld

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.
