- Page 4 1. Summary Kjeldahl Digestor, adopted with globally advanced high temperature infra-red duct radiant heating technology and MPU control platform, is characterized by its accurate temperature control and fast temperature rise. The temperature rise, divided into linear temperature rise mode and curved temperature rise mode, allows storage of 500 groups of digestion solutions.
- Page 5 1.1 Features: The heating efficiency is greatly improved by the infrared radiation and graphite block, which ⚫ guarantees uniform temperature. Mass storage: 500 groups of digestion solution, each of them has 25 temperature spots at most. ⚫ Two modes of heating: straight line and curve; twenty heating programs in total; 1-99 intervals are ⚫...
- Page 6 Operating procedures: • Power on the instrument • Put the digestion tubes loaded with sample in the rack, and install the rack on the Graphite Digester, which connects the Exhaust System. Connect and start the Exhaust System to the Kjeldahl Digestor and open the condensate water switch. Check the connection and condensate water.
