Automatic Kjeldahl Protein/ Nitrogen Analyzer

Automatic Kjeldahl Protein/ Nitrogen Analyzer
Model: PT-K1160

PT-K1160 Automatic Kjeldahl Protein/Nitrogen Analyzer is unique in its intelligence, efficiency, energy saving and data sharing, bringing more new experiences to users. The product can be widely used in the fields of food processing, feed production, tobacco, animal husbandry, soil fertility, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision and other fields of nitrogen or protein determination.


Automation, Fully automatic distillation, titration, calculation, printing, waste disposal, fault self-test and can be paired with 24 positions auto sampler for true unattended operation, making the whole experiment process simple and efficient.

Compliance with FDA 21CFR Part.11 and GMP, it have the function of authorization management, account management, experiment data traceable password-aging and editing protection, etc.

High accuracy, burette accuracy can be adjust from 0.2 to 1μL/Step.


With side-distillation titration and variable-speed titration technology, reducing experiment time by one-third

New Android operating system, easy to use, powerful, with 10 inch high-definition color touch screen, real-time control of the entire experimental process

With batch testing function, it makes the batch sample experiment operation simple and simple, reducing test time

Monitoring the condensate effluent temperature in real time to ensure complete condensation of the sample, ensuring the test results are

accurate and reliable

Privilege grading function, which can realize data traceability management and meet the requirements of GMP and 21CFR Part11

The titration module is used to titrate the receiving liquid, the titration result is more accurate, and the titration precision is higher.

The titration graph displays the online monitoring of the entire experimental process in real time, and the experimental method can be adjusted in real time to improve the test accuracy and efficiency.

Up to 24 positions auto sampler, the K1124 auto sampler does not require a separate power supply and is directly connected to the K1160

fully automatic Kjeldahl analyzer. The entire system is more energy efficient.

24-bit injection port, the cleaning position is separated from the test position, completely eliminating the possibility of cross-contamination during distillation

Ultra-large capacity solvent tank, which can meet 500 experimental analysis in one fill, effectively improve laboratory efficiency

Testing report can be customized and output by pdf or print.

All sample weight weigh by balance can be output directly into K1160 for analysis(specified model).

Color sensor can be adjust by RGB model, compliance with AOACISOEPAUSP etc.
