Automatic Kjeldahl Nitrogen analyzer

Automatic Kjeldahl Nitrogen analyzer

Short Description:

Brand:NANBEI

Model:KDN-04A

Kjeldahl Nitrogen Analyzer is a special instrument for detecting nitrogen content in agricultural and sideline products such as seeds, dairy products, beverages, feed, and soil. The nitrogen analyzer is an instrument that calculates the protein content by measuring the nitrogen content in the sample based on the principle that the nitrogen content in the protein does not change. Because the method of measuring and calculating protein content is called Kelvin nitrogen determination method, it is called Kelvin nitrogen analyzer, also known as protein analyzer and crude protein analyzer. The instrument is also widely used in food plants, drinking water plants, drug inspection, fertilizer determination, etc.

Characteristics

1. Using microcomputer to control the process
2. Automatically control the distillation, add water, control the water level, and cut off the water supply
3. Multiple safety protections: digestive system safety device, steam generator water shortage alarm, water level detection fault alarm
4. The instrument shell is made of special plastic-sprayed steel; the working area is made of ABS anti-corrosion board. Avoid chemical reagent corrosion and mechanical surface damage, acid and alkali resistance.
5. Once a fault is detected, the control system will automatically power off
6. Using tap water source, wide adaptability and low test requirements.
