Kjeldahl Nitrogen Analyzer ZDDN-II

   Kjeldahl Nitrogen Analyzer ZDDN-II

Features:

1.ZDDN-II Kjeldahl Nitrogen Determination Instrument, adopts microcomputer for process control, including manual mode and automatic mode, which can be set and switched by yourself according to your needs:

In automatic mode: add alkali, boric acid, distillation and ammonia absorption at one time, the volume of boric acid and alkali as well as the time of distillation and absorption process can be set by yourself.

Manual mode: adding boron, adding alkali and distillation absorption of the three processes can be operated manually, volume, time control, to meet the needs of professional users.

2. Large dot-matrix LCD display, full Chinese menu, touch buttons, simple and convenient operation.

3. Automatic distillation control, automatic water filling, automatic water level control, automatic water stop.

4. All kinds of safety protection: digestive tube safety door device, steam generator water shortage alarm, water level detection fault alarm.

5. The number of storable operating procedures: 250.

6. The instrument shell is made of special plastic spraying steel plate, and the working area is made of ABS anticorrosive plate, which prevents chemical reagents from corroding and mechanically damaging the surface, and is acid and alkali resistant.

7. Water level detection, low water level alarm, automatic power-off. Instrument control system failure can automatically power off.

8. Standard equipment does not include digestion furnace, digestion furnace is optional.

Technical parameters:

Optional device: Digital digestion furnace 

Automatic Kjeldahl Nitrogen Determination can be equipped with digestion furnace with different holes (Standard accessories not include digestion furnace).

4, 8, 12 and 20 holes digital digester are available in . Digestion of one batch of samples takes about 60-90 minutes (depending on the nitrogen content).

Hazardous gases such as SO2 escaping from the digestion are discharged from the water into the sewer via a collection tube and an extraction tee.

According to the principle of classical Kjeldahl nitrogen determination method, it is widely used in the elimination of feed, grain, food, soil, fertilizer, water, sediment, chemicals dairy products, brewing, sugar, drugs, coal, rubber and other substances, with the characteristics of accurate testing, safe and reliable, easy to operate and so on.

Features:

1、The whole machine chassis is made of special plastic spraying steel plate, and the working table is made of stainless steel material;

2、It has good corrosion resistance and beautiful color;

3、Double shell design, air insulation layer and aluminum silicate insulation layer, double insulation effect;

4、The whole machine has multiple protection against over-voltage, over-current, overheating and so on;

5、The whole machine is small and beautiful, simple operation, easy and quick to use.
