Product Details

CN8900 automatic sampling automatic Kjeldahl nitrogen analyzer is developed based on the classic Kjeldahl nitrogen determination method. The analysis methods are titration technology and color method to determine the end point, which conforms to relevant international standards. The product is equipped with 20/24/40-position automatic sampling system, which realizes unattended automatic analysis, has automatic discharge of digestion waste liquid, and is equipped with a refrigeration system without consuming tap water…...

Characteristics

20/24/40 position automatic sampling system - ①The sample digestion bracket can be directly placed in the injector, which is convenient and fast; ②The digestion tube is automatically detected in place; ③One-click to complete the automatic analysis of 1-40 samples

The operating system adopts a 10-inch color touch screen, and the man-machine dialogue is simple and easy to operate and learn. The three-level user management meets the relevant certification requirements, and the operation traceability query system.

The system automatically shuts down after 60 minutes of unattended operation, saving energy, safety, and peace of mind. Choose R, G, B coaxial tricolor light source and tricolor sensor, with wide color adaptability and high precision.

Automatic adjustment of R, G, B light intensity for analysis samples of different concentrations. The three titration curves of R, G and B can observe the change of the sample during the titration process and provide help for the analysis.

16M data storage capacity can store 100,000 sample data for reference, 5.7CM automatic paper cutting thermal printer. Automatic discharge of digestive waste liquid reduces labor intensity of staff.

The internal standard of the titrant concentration eliminates the systematic error of the difference between the human and the instrument, with high precision and convenience.

The steam flow can be adjusted arbitrarily from 40%--100% to suit different concentrations of samples. Automatic upload of sample weighing data, reducing tedious manual input one by one and input errors.

Shut down and automatically clean the alkali pipeline to prevent pipeline blockage and ensure the accuracy of liquid supply. Cooling water flow monitoring prevents insufficient water flow causing sample loss and affecting analysis results.

Steam overpressure alarm and shutdown to prevent accidents. Sample over-temperature alarm and shutdown to prevent sample temperature rise and affect analysis data.

Sample over-temperature alarm and shutdown to prevent sample temperature rise and affect analysis data. Metal material (304 stainless steel) steam boiler has stable performance, reliability and pressure resistance.

The leakage protection system prevents leakage and electric shock to ensure the safety of operators. Absence of digestive tube system does not add reagents or heat to prevent reagents and steam from hurting people.

Titration-while-distillation mode saves analysis time and reduces ineffective distillation power consumption.
