Introduction: KDN-818 Automatic Nitrogen Meter, with the classic Kjeldahl method as the working principle, safe, fast, accurate, low consumption, user-friendly. A variety of operating modes: Automatic mode: Distillation titration fully automatic, without personnel duty, automatic calculation of protein analysis results; Manual mode: add alkali, add acid, add distilled water, distillation can be controlled separately, Manual titration can also be mixed operation. The difference is that you can set the user approved color as the endpoint; the other in the conventional color decision sensing based on the company's original color filtering technology coupled with adjustable jitter decision function makes the color method to determine the precise endpoint Correct, color difference and curve display directly, so that users can see the determination of the instrument process. Another built-in flexible open titration debugging system, the user can easily set the titration parameters, fully demonstrated 818 system logic capabilities. 818 design and development into the fiber-seized more than 30 years of manufacturing experience and the majority of users of automatic nitrogen determination of the desire to apply to the test results of higher precision users. Features: 1. International standards Kjeldahl method: concentrated sulfuric acid digestion, alkaline steam distillation, boric acid absorption, the indicator titration endpoint color determination 2. Using continuous titration, titration can be unlimited, no need to pump reagent back and forth 3. The end of the adjustable: you can set any user-approved color as the end point 4. Three-phase titration speed automatically involved, to ensure that both fast and accurate 5. Pre-titration function: Set the titration rate for a sample of known concentration pre-titration 6 automatic waste cleaning 7. Working methods: manual one, a variety of manual functions 8. Display mode: 7-inch LCD ultra-fine color widescreen display 9. Control Panel: Touch 10. Dedicated reagent bucket, with liquid level alarm indication 11. Anti-emergencies: can continue testing after power off, does not affect the current sample test results, to avoid unexpected events lead to scrapped samples 12. Splash-proof tube material: a high-performance acid-base plastic mold forming a strong, good sealing performance, alkali-resistant than glass, long life 13.
