Berghof presents its top loader speedwave four microwave with improved mid IR temperature sensor and touch screen. Since 2004 the company has been the only manufacturer to offer patented, non-contact pressure measurement in all vessels in the form of the speedwave microwave digestion system in addition to the non-contact mid-IR temperature measurement. This ensures that all vessels are under control at all times. This applies in particular to fast exothermic reactions. Both user safety and the reproducibility of digestion are significantly increased. No sensors have to be connected to the pressure vessel, so that handling is very simple. The pressure vessels themselves consist of only few parts and can be locked or opened in only a few seconds. Since they are entirely made from TFM, they are resistant to chemicals and have a service life of 3-5 years.
