Product brief
The YSC218 insoluble solid specific Karl Fischer moisture analyzer fills the gap in China. It adopts a unique needle design, which can achieve both carrier gas input and water vapor output in one operation. At the same time, due to the new gas path design, water vapor transmission can be achieved with extremely low flow rate. Each injection only requires changing the sample bottle for easy operation, without waiting for the sample bottle to cool down before changing the bottle cap. The detection accuracy can reach ppm level, which is very suitable for industries such as lithium batteries, plastic particles, and petrochemicals that have high requirements for moisture detection.

1. The high-precision Coulomb method moisture analyzer is used in conjunction with a Kjeldahl heating furnace, which can detect a minimum of 3 μ g of water with an accuracy of ppm level;

Two hollow core gas injection needles and gas delivery pipelines with heating function, zero dead volume water vapor does not condense, making operation simpler and greatly improving the accuracy and repeatability of the instrument;

3 high-definition capacitive touch screen, implementing display measurement parameters, concise and clear functional menu, comprehensive parameter display, easy and fast operation;

4 built-in 5 methods to choose from, 8 calculation formulas for convenient sample testing, custom sample units such as%, ppm, mg/kg, etc. result units are more user-friendly;

The 5 system detects moisture in the environment in real-time, accurately deducts drift, and uses real-time dynamic impedance method to determine the titration endpoint, resulting in more accurate measurement results;

The maximum temperature of 300 ℃ can meet the testing requirements of most samples, and the airflow can be adjusted from 0-100ml, suitable for samples with various water release rates;

Easy to operate, users only need to set the appropriate temperature and flow rate, put the sample into the pre prepared sample bottle, put it into the heater, then insert the transfer needle into the silicone pad of the sample bottle, and click on the instrument to start measuring.

8. There is no need to wait for the previous sample bottle to cool down before proceeding to the next sample measurement. During the process of replacing the sample bottle, the sample bottle always remains sealed, resulting in higher and more accurate measurement efficiency. Especially for samples with strong moisture absorption, there is no need to worry about the interference of moisture in the air.

9. Use headspace injection method to ensure that each measurement is conducted usingThe "new" sample bottle has no cross infection detected during sample testing. The sample bottle has a small volume, ensuring a small dead volume and background moisture value. The independent sealed sample bottle does not require sample transfer during measurement, resulting in more accurate results. The screw cap sample bottle does not require specialized and expensive capping and opening devices, making it very convenient to use.

10 headspace sampling technology, only gas enters the reaction cup of the moisture analyzer, without contaminating the reaction cup and electrolytic electrode;
