Overview

The V310S-KHF sealing silicone base moisture tester uses a combination of a Karl Fischer oven and a Coulomb method moisture analyzer to detect moisture in sealing silicone base materials. It is currently a commonly used method and has been used in dozens of sealing silicone manufacturers in China, including detecting moisture in silicone sealant base materials, MS silicone data, nano calcium carbonate, heavy calcium carbonate, white oil, titanium dioxide and other samples.

Product Details

Sealed silicone base material moisture testerUsing an empty core injection needle design, one operation can achieve both carrier gas input and water vapor output. At the same time, due to the new gas path design, the transmission of water vapor can be achieved with a very small flow rate. Each injection only requires the replacement of the sample bottle, which is convenient to operate without waiting for the bottle cap to cool down. The detection accuracy can reachppmGrade, very suitable for industries with high requirements for moisture detection, such as sealing silicone base materials, lithium batteries, plastic particles, petrochemicals, etc.

1Hollow core gas needle injection and gas delivery pipeline with heating function, no dead volume of water vapor or condensation, simpler operation, and greatly improve the accuracy and repeatability of the instrument;

2There are 5 built-in methods to choose from, 8 calculation formulas for convenient sample testing, and customized sample units such as%, ppm, mg/kg, etc., making the result units more user-friendly;

4The temperature can reach 300 ℃, which can meet the testing requirements of most samples. The airflow can be adjusted from 0-100ml, suitable for samples with various water release rates;

4There 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.

5Headspace sampling technology allows only gas to enter the reaction cup of the moisture analyzer without contaminating the reaction cup and electrolytic electrode;
