Purpose overview

The automatic chloride ion potentiometric titrator is an intelligent chloride ion automatic potentiometric titrator developed according to 11.1 chloride ion content potentiometric titration method in GB/T8077-2012 "Concrete Admixture Homogeneity Test Method". It is mainly used for chemical analysis of various components in various industries such as inspection agencies, cement enterprises, concrete mixing stations, scientific research institutes, petrochemical, pharmaceutical, drug inspection, metallurgy and other laboratories. It has the advantages of easy operation, high accuracy and intelligence.

Product advantages: why we call it "automatic" cement chloride ion potentiometric titrator

1. The world's first successfully developed truly fully automatic function. During the whole experiment (calibration of silver nitrate solution, blank experiment and sample calibration), no calculation is required, and the final result is directly displayed.

2. High measurement accuracy, using imported control chip and micro pump, the titration accuracy range is 1ml~0.01ml, which can be adjusted arbitrarily according to user requirements.

3. In order to improve work efficiency and save test time, the instrument has the functions of setting quick titration and stopping titration (the first in China).

4. Save test time. Under the condition of adding 0.1ml/time, complete the fast drop test within 3 minutes for one sample, saving test time.

5. Automatic cleaning function. This machine has a unique cleaning function key. When starting to use and replacing the silver nitrate solution, choose 1-3 times of cleaning according to the actual situation on site to reduce the impact of the change in the concentration of the silver nitrate solution on the experimental results.

6. It has a wide range of applications. The instrument has the function of continuous titration and continuous liquid absorption. The instrument adopts an integrated automatic reversing valve device, which is controlled by a microcomputer. It does not need manual control and switching of the reversing of the injection or rehydration method to improve the measurement accuracy of the titrant. It has the advantages of high degree of automation. The instrument uses a large-capacity sampling pump (25ml) to measure both low-content chloride ions in cement and high-content samples.

7. The comprehensive function of the instrument is powerful, and it can also perform various titrations such as acid-base titration, redox titration, precipitation titration, comprehensive titration, non-aqueous titration, etc. It has functions such as pH measurement, potential measurement, and temperature measurement.

8. Switch between Chinese and English (the first in China), in order to adapt to the convenience of domestic enterprises to set up factories abroad.

9. The design of the instrument is unique. In order to adapt to the harsh environment of the laboratory in the cement industry, it adopts the design of ten buttons on the LCD screen (each button has a life span of 2 million times). Its advantages are anti-corrosion and anti-shock. The whole machine adopts a one-time injection molding process. It has the advantages of corrosion resistance, no rust, light weight, beautiful appearance and long service life.

10. The instrument is equipped with a large-capacity SD memory card, which supports GLP specifications. According to the capacity of the SD card, it can be stored wirelessly. The test results are automatically generated and stored in files every day, which is convenient for users to store and query data, and can be used on the computer. This instrument presents an operation video U disk for the convenience of users.
