Technical parameter model DHJ-7 series power supply 220V maximum power 3000W maximum temperature 250 ℃ temperature control accuracy ± 2.0 ℃ sample quantity 24,48 (can be specially designed) electric heating plate size mm 380 × 570 × 50 (can be specially designed) Main features comply with European standards: CEM 89/336/CEE-LVD 73/23/CEE-EN 61010 is cleaner: it adopts a thick PTFE coating inside, which is corrosion-resistant and pollution-free. It is more efficient: the advanced integrated surrounding heating method saves more electricity than traditional electric heating plate digestion. It is more economical: the cost of use is low, the digestion process is fast, convenient and uniform. The material has high thermal conductivity, and the temperature difference between samples is less than ± 1.5 ℃. It quickly reaches the set temperature and saves time. The unique digital serial port design allows for programmed heating, high and low temperature alarms, and automatic heating stop for remote control. 5. Original imported from Germany
