Metrax GmbH was founded in 1973 and initially focused on the manufacture and development of bubble baths. Over the years, the portfolio was expanded to also include staplers for BOSCH, massage devices and devices for electrotherapy, and in 1989 the first defibrillator was developed. Today, Metrax GmbH concentrates fully and exclusively on the production, development and distribution of defibrillators. These include, for example, the M250 series launched in 2004 and the M290 series in 2006. Our first full-featured monitor device, the DefiMonitor EVO, was launched in 2013. Since February 2017, Metrax GmbH has been part of the Chinese Yuwell Group.
