GMS4000 Gas network detector


The device innovation GMS 4000 is the universal device for gas leak detection, network control and gas analysis. With infrared measurement technology, the measuring instrument can determine natural gas and CO2 exactly and without cross-sensitivities. The GMS 4000 detects heavy gas, oxygen, hydrogen sulfide and carbon monoxide (optional sensors). In addition, the ethane / propane analysis with data storage of the measurement results is possible.

Parameter/Features Inquiry
  • Features

    A Bluetooth interface and a GPS receiver are available. Data storage with the GPS coordinates and the transfer of the data to the PC to document the route are also possible. The device can of course be controlled wirelessly with the tablet PC. With the new lithium-ion batteries, the operating time and reliability of the device are unmatched.

    The GMS 4000 offers even higher results accuracy even with changing tasks, as it can be adjusted to the different measuring tasks and changed measuring environments. The device monitors the aspirated volume flow and can adapt to the changed measuring environment and preset, monitor and readjust the volume flow. In addition to reliable measurement results, optimal stability and consistent response times are achieved.

    The user is offered maximum maintenance friendliness and maximum availability because the intelligent measuring sensors can be quickly exchanged if necessary without configuration problems. Thanks to the menu navigation in conjunction with the automatic measuring range selection, the GMS 4000 measuring system can be operated easily and safely at any time, even by inexperienced users. All that is required for commissioning is a task in the main menu, e.g. Gas detection, to be selected, and the measuring device then automatically sets sensor selection, measuring range, pump output and alarm message according to a defined program.

    The GMS 4000 gas detector and gas concentration measuring device has:

    Large LCD display with automatic lighting

    Digital and analog display possible

    Very simple operation through automatic measuring range and menu control

    Selective CH4 measurements with clear measurement results

    Selective CO2 measurements with clear measurement results

    Electrochemical measurement technology for O2, CO, H2S (optional)

    Gas analysis during operation ethane and propane from a few ppm

    Measurement data storage for inspections, gas analysis and individual measurements

    Data storage with GPS coordinates, date and time

    Multifunctional uses for gas detection on pipe networks

    Determination of damage points in drill / probe holes

    Concentration measurements in pipelines

    Long operating time thanks to lithium-ion batteries

    Integrated GPS receiver with data storage

    Integrated bluetooth interface

    Free PC software for file transfer

    Extremely robust for tough practical use

    Robust and lightweight metal housing (aluminum)

    Long-term guarantee of 5 years

    Individual configuration according to customer requirements


    The applications are preset to the required alarm level, pump performance, the measuring ranges and sensor systems are selected automatically according to the selected application. The selection functions can easily be changed and adapted to your requirements. Subsequent changes are possible from a PC.

    In order to use the device in conjunction with a PC, there is free display and control software for each device (e.g. for a tablet PC). Of course, the optional wireless connection with the Bluetooth interface is available here.
