    EX-TEC HS 680

    The EX-TEC HS 680 is perfect for detecting leaks in underground natural gas pipelines. Its multi-array sensor suite includes infrared for pin-pointing the exact location of leaks along the pipeline. This system avoids unnecessary and costly excavations. Its integrated ethane-C2H6 detector provides easy verification whether the gas leaking from the underground is a natural gas product from the pipeline or simply a natural occurring biogas (i.e., marsh or swamp gas). Precision leak pinpointing is achieved using the optional oxygen-O2 sensor. The O2 sensor indicates the minimum O2 level while simultaneously measuring for the maximum methane-CH4 level. This "minimum" with its smaller diffusion area in conjunction with the maximum methane indication provides easy pinpointing of complex leaks.


    VARIOTEC VT series detectors and their multiple options allow users to detect natural gas along the pipeline and aid with leak pinpointing. The VARIOTEC 460 & 480 EX can be equipped with optional ethane-C2H6 analysis which confirm the leak origin (distinguish between natural gas product or biogas, i.e., marsh & swamp gas). The VARIOTEC series provides users with affordable instruments for almost any gas detection application.


    The PORTAFID M3K is a portable flame ionization detector that is reliable and highly accurate and resistant to interference from moisture and is hydrocarbon specific. The 0.4 liter fuel gas bottle is carried in an economic back harness.


    The VARIOTEC EGA ethane gas analyzer is a perfect instrument for determining whether a gas leak is from a natural gas pipeline or simply a naturally occurring biogas (i.e., swamp or marsh gas). This information can prevent an expensive excavation from occurring. The VARIOTEC EGA can quickly and easily confirm the origin of the gas leakage.

    The VARIOTEC EGA analysis utilizes the fact that Natural Gas from a product pipeline contains ethane-C2H6 but biogas does not have ethane present.

    SNOOPER mini

    The SNOOPER mini is a small but very robust compact gas leak detector specifically designed for inspection of accessible gas lines and fittings. Modern gas leak detectors have considerable advantages over leak detection spray techniques that were used in the past. The SNOOPER mini indicates the presence of gas and also indicates the concentration at the leak. The SNOOPER mini is perfect for gas suppliers and contractors that are inspecting pipe installations and fittings inside or outside. Also the SNOOPER mini is ideal for fleet mechanics that routinely inspect and repair vehicles with LPG/NG on board.

    The SNOOPER mini is available with sensor to indicate methane-CH4 or propane-C3H8

    Multitec 560

    The Multitec 560 is a combination gas warning and measuring device. When used as a gas warning instrument it reliably and automatically detects gases which are toxic and hazardous to workers. It also records and documents the composition of biological process gasses. Infrared measuring technology ensures accurate methane and carbon dioxide readings. The Multitec 560 is ideal for inspection of area work atmospheres (e.g., engine pits, silage tanks, shaft construction, etc.). It detects explosive and toxic gases ensuring worker safety at all times. Also the Multitec 560 is perfect for monitoring biogas production in plants. The Multitec 560 can record and analyze the gas compositions for process optimization.

    The gas warning function (ExTox) records CH4, CO2, O2, CO and H2S and can be set to alarm and pre-set values. The Multitec 560 can also be used virtually anywhere in the plane as a gas warning device.

  • Gas Detection - Laser


    The Laser Methane LMm from Pergam offer users the ability to detect methane remotely. What once was time consuming and a resource draining procedure can now be completed in a fraction of the time. This is accomplished by utilizing the best in Tunable Diode Laser Absorption Spectroscopy (TDLAS).
