Metrax GmbH was established in 1973, originally specialising in the manufacture and development of bubble baths. Over the years, the company expanded its portfolio to include staplers for BOSCH, massage devices, and electrotherapy equipment. In 1989, Metrax developed its first defibrillator. Today, Metrax GmbH is dedicated entirely to the production, development, and distribution of defibrillators. Notable products include the M250 series, introduced in 2004, and the M290 series, launched in 2006.
