（China）YY9870 Automatic Kjeldahl nitrogen analyzer

Product Features:

1) The control system uses 7-inch color touch screen, Chinese and English conversion, simple and easy to operate

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

3)★ System 60 minutes unmanned automatic shutdown, energy saving, safety, rest assured

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

5) Titration system uses R, G, B coaxial light source and sensor, wide color adaptation range, high precision

6)★R, G, B three-color light intensity automatic adjustment system is suitable for sample analysis of different concentrations

7) The titration speed is arbitrarily set from 0.05ml/ s to 1.0ml/ s, and the minimum titration volume can reach 0.2ul/ step

8) German ILS 25mL injection tube and linear motor with 0.6mm lead form a high-precision titration system

9) Clear installation of titration cup is convenient for users to observe the titration process and titration cup cleaning

10) Distillation time is freely set from 10 seconds –9990 seconds

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

12)5.7CM automatic paper cutting thermal printer

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

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

15) Leakage protection system to ensure the safety of operators
