Following the merger of the companies GREISINGER electronic, Honsberg Instruments and Martens Elektronik in 2009, GHM Messtechnik was established, thus providing enhanced competence for all aspects of measurement and industrial electronics.

In March 2010, Imtron Messtechnik was integrated as fourth company into the GHM group, in July 2013 these companies were merged to form GHM Messtechnik.
At this time was also the new sales and training center implemented at Erolzheim. And we found a new partner for regulation equipment, company T&A Telemetrie & Automation, which joined our group in March 2014.
