Product Description
Features:
1.KDN-520 full automatic Kjeldahl azotometer is used for process control by microcomputer, which can be chosen by manual and automatic operation mode to facilitate customers' selection.
2. Automatic mode: use one key to complete automatic water filling and automatic water level control; automatic dilution; automatic acid dosing; automatic alkali dosing; automatic distillation. Customers can set different automatic working hours according to different samples. In the automatic operation mode, the number of reagents can be increased by using the suspension function.
3. Manual mode: the customer can select manual mode to make 4 processes separately: dilute, add acid and alkali, and distil. Time and dosage can be controlled by itself.
4. Storage data: it can set 999 operational processes at most. There are eight independent control stages under each process (the data export and analysis function can be extended at the same time)
5. The instrument is equipped with 4 independent import micro-pumps to make control, ultra-silence and high flow accuracy. The internal uses imported silicone tubes, with long service life, and easy to replace.
6. Display mode: 5.5-inch LCD display, Chinese and English switching, and touch button make it is easy to be operated.
7. Various alarms for safety protection: the safety door device of the digestive tube; alarm for steam generator is short of water, and alarm for water level detection failure; safety alarm for excessive current of instrument.
8. Current display and current protection setting function: there is a working current display on the LCD screen of the instrument, and the current value can be set. When the current is too large and exceeds the set value, the device can automatically alarm and power off.
9. The shell of the instrument is made of special plastic steel, and anti-corrosion, transparent and safe protection door can observe the whole distillation process.
10. It is suitable for various water sources with wide adaptability.
