Product Introduction
▲ Famous for its high test recovery rate beyond most imported products, it participated in the drafting of GB/T22923-2008 national standard for testing nitrogen content in fertilizer; It has two national patents (one invention patent and one utility model patent);
▲ Solving the worldwide problems that nitrate nitrogen cannot be tested by instruments and existing instruments cannot meet the test requirement due to the high requirement of the fertilizer industry on the recovery rate of nitrogen content samples, it has been further invited for drafting of the international standard.
▲ It uses the world’s leading technology of determining the titration endpoint through a color sensor. Compared with photocell detection, the technology has the obvious advantages of accurate endpoint judgment, strong anti-interference ability, long life, no need to put the titration system in a dark room, convenient operation and observation, etc.; and compared with potentiometric titration testing, it has obvious advantages such as no temperature drift at the titration endpoint, no preheating and calibration.
▲ Strict design and rigorous material selection ensure high test precision and high recovery rate.
▲ With PC and network advantages, the apparatus is provided with an RS232 interface (standard) and a wireless Bluetooth interface (optional), connected to a computer that automatically generates a test report with comprehensive test information by matching special data processing software, and enhanced computer control software is available.
▲ On the basis of the model K06B, a high-nitrogen sample testing function is added to the model K06C.
Main Characteristics
1. Full automation is realized in the whole distillation and titration process, including automatic addition of absorbing liquid and lye, automatic distillation, automatic titration, automatic emptying and cleaning of the digestive tube (optional), and automatic analysis and calculation of digested samples that are put on the apparatus, so that maximum convenience is brought to operation personnel.
2. Determining the titration endpoint through a color sensor, resulting to accurate judgment, strong anti-jamming capability, visual titration process, no preheating and calibration.
3. In line with the national/international standard
4. Microcomputer intelligent control, LCD large screen display, a menu man-machine dialogue operation interface
5. An imported high-precision (2ul) titration system with automatic speed control function is adopted, so the results are accurate and reliable.
6. The steam detection device automatically monitors steam pressure to guarantee work safety.
7. The test tube and safety gate automatic detection system effectively prevents wrong operation. PTFE bellows pumps controlled by separate stepping motors are adopted to add reagent and have excellent resistance to corrosion and particle blockage as well as accurate and stable liquid addition without calibration; the liquid adding is directly set to be volume with the unit ml.
8. It can store 2,000 sets of test data.
9. The RS232 serial port is used to complete the exchange of information with an upper computer, and the test result is output in the form of report.
10. Bluetooth wireless transmission in cooperation with report processing software will make your work easier (optional).
11. ABS engineering plastic case is resistant to corrosion, water and electricity, safe, and more suitable for the chemistry lab environment.
12. It solves the problem that nitrate nitrogen samples cannot be tested by instruments.
13. It also solves the worldwide problem that the test recovery rate of high-nitrogen samples cannot meet the fertilizer standard.
