Declarations and Certificates

  • Memberships and Partnerships


    Electricians underscore their competence to customers with ZVEH’s E-Seal logo. GOSSEN METRAWATT supports the E-Seal and E-CHECK – the recognized seal of approval for businesses specialized in electrical work involving electrical systems and equipment.

    E-CHECK Partner

    Needles to say, our test instruments comply with the requirements for performing the E-CHECK - for safe electrical systems and devices.

    We promote research and the transfer of knowledge in the field of metrology by means of our membership in the Helmholtz-Fonds e. V.


    Recognised Component Mark

    The Recognised Component Mark from UL (left) may be used for components parts that are part of a larger product or system. Many of our custom power supplies have this certification.

    Automation Valley

    Innovation by cooperation with partners of control and automation engineering, possible by membership in Automation Valley.


    We are member of AS-INTERFACE.


    We belong to PROFIBUS User Organization


    LonWorks-technology refers to a universal automation network and is a worldwide standard for the automation of buildings and industrial plants.
    Our energy management systems and measuring transducers are equipped with this interface.

    M-Bus / L-Bus

    For the development of M-Bus applications we consider the requirements of the M-Bus User Group at Paderborn University.
    L-Bus devices work with the same protocols as M-Bus devices, but with very low signal levels.


    HART - Highway Addressable Remote Transducer - is an open communication protocol for industrial measuring instruments - many of our transducers can work with this protocol.


    The Controller Area Network is used in the automotive industry, the factory automation and for machine control. We support this with our temperature controllers.


    MODBUS Protocol is a messaging structure developed by Modicon in 1979, used to establish master-slave/client-server communication between intelligent devices.
    It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment. Our energy management systems and transducers are also available with this protocol.


    We incorporate our know-how into national and international safety standards by means of active participation in the development of normative documents
