Fully Automatic Kjeldahl Apparatus UKA-9870 Series
Automatic Kjeldahl Apparatus Feature:
1. Operating system: 7.5-inch color touch screen with man-machine dialogue mode easy to operate, easy to learn.
2. Titration sensor: Choose R, G, B three color sensors, with wide range of color adaptation, high precision and quick response
3. Titration curve: The titration curves of R, G and B can timely observe the changes of samples in the titration process, providing help for the analysis process.
4. Titration pump: The titration system – “plunger titration pump” – is composed of German linear motor and injection needle, which has high control precision and good stability.
5. Titration volume verification: Verify the accuracy of titration system to ensure the accuracy of analytical data
6. Protein coefficient query: This instrument contains the protein coefficient query table for users to consult, inquire and participate in the system calculation, which is convenient for users to use.
