Introduction 

1.Features 

a. The heating body (module) adopts the infrared quartz tube, which can withstand strong acid and 

alkali, and prevent explosion and long life. 

b.  The  heat  area  of  the  digestive  tube  is  large,  the  temperature  difference  is  small,  the  sample 

digestion is good, and the thermal efficiency is high. 

c. Temperature control adopts a new generation of digital display temperature control device. 

d. Beautiful appearance, light structure and easy to use. 

 

2.Technical Parameters 

a. Determination quantity: 8 / batch; 

b. Measurement of sample size: the solid is less than 5g, and the liquid is less than 20ml/; 

c. Capacity of digestive tube: 300ml standard; 

d. Determination range :240mgN; 

e. Temperature control range:at room temperature to 550 ℃; 

f. Heating rate: 30 degrees /min; 

g. Temperature control accuracy:±1℃ 

h. Power consumption: digester (8 holes 2000W); 

i. Power source: 220 (V) + / -10%, 50~60HZ; 

j. Appearance size: 435*270*225 (mm); 

k. Weight: 8.6kg; 

In accordance with the principle of the kjeldahl method, the apparatus is widely used in the 

digestion  of  food,  feed,  food,  dairy  products,  beverage,  soil,  water,  medicine,  sediment  and 

chemical.  Test  precision,  safe  and  reliable,  easy  to  operate,  the  harmful  gas  such  as  SO2  of 

digestive tube overflow at the same time, through the digestive sewage collection on the furnace 

tube  through  the  suction  filter  pump  from  the  water  into  the  sewer,  and  effectively  restrain  the 

harmful gas to escape.
