（China）YY9830A Automatic Kjeldahl Nitrogen Analyzer

Product Features:

1) The control system uses a 10-inch color touch screen, Chinese and English conversion, easy to operate

2) Three-level rights management, electronic records, electronic labels, and operation traceability query systems meet relevant certification requirements

3) The system automatically shuts down in 60 minutes without operation, saving energy, safety and rest assured

4)★ Input titration volume automatic calculation analysis results and storage, display, query, print, with some functions of automatic products

5)★ The instrument built-in protein coefficient query table for users to consult, query and participate in the system calculation, when the coefficient =1 analysis result is “nitrogen content” when the coefficient >1 analysis result is automatically converted to “protein content” and displayed, stored and printed

6) Distillation time is freely set from 10 seconds to 9990 seconds

7) The steam flow rate can be adjusted from 1% to 100% to apply different concentration samples

8) Automatic discharge of waste liquid from the cooking pipe reduces the labor intensity of the staff

9)★ Shut down automatic cleaning alkali pipeline to prevent pipeline blockage and ensure liquid supply accuracy

10) Data can be stored up to 1 million pieces for users to consult

11)5.7CM automatic paper cutting thermal printer

12) The steam system is made of 304 stainless steel, safe and reliable

13) The cooler is made of 304 stainless steel, with fast cooling speed and stable analysis data

14) Leakage protection system to ensure the safety of operators

15) Security door and security door alarm system to ensure personal safety

16) The missing protection system of the deboiling tube prevents reagents and steam from hurting people

17) Steam system water shortage alarm, stop to prevent accidents

18) Steam pot overtemperature alarm, stop to prevent accidents

19) Steam overpressure alarm, shutdown, to prevent accidents

20) Sample overtemperature alarm, shutdown to prevent sample temperature rise and affect the analysis data
