3. Product features

1. JC-QN-08C automatic Kjeldahl nitrogen analyzer adopts microcomputer for process control, including manual mode and automatic mode, which can be set and switched according to your needs
; The whole process of boric acid, adding alkali, distillation and ammonia absorption, the volume of adding boric acid and alkali and the time of distillation and absorption can be set by yourself.
In manual mode: the three processes of adding boric acid, adding alkali and distillation and absorption can be manually operated separately, and the volume and time can be controlled by themselves to meet the needs of professional users
. Convenience.
3. Automatic distillation control, automatic water addition, automatic water level control, automatic water stop.
4. Various safety protections: digestive tube safety door device, steam generator water shortage alarm, water level detection fault alarm.
5. The maximum number of operation programs that can be stored is 250.
6. The shell of the instrument is made of customized plastic-sprayed steel plate, and the working area is made of ABS anti-corrosion panel, which is resistant to chemical reagent corrosion and mechanical damage to the surface, and is resistant to acid and alkali.
7. Water level detection, low water level alarm, automatic power off when the instrument control system fails.
8. The standard digestion furnace.
