True density analyzer

TD-2200 true density analyzer

Principle Introduction

The TD-2200 true density analyzer uses the gas replacement method to pass a small molecular diameter inert gas through the sample compartment, uses Poma's law as a test software analysis model, and uses a high-precision sensor to measure the volume of gas excluded from the sample in the sample compartment. Thus the true density is calculated. The gas replacement method eliminates the possibility of the liquid method dissolving the sample, and has the advantage of not damaging the sample. (The test gas is generally high-purity helium, high-purity nitrogen can also be used, but make sure that the material being tested does not react with nitrogen)

main feature

1. High test accuracy and good accuracy, solving the problem of dissolving the sample by the immersion method;

2. The entire test process will not change the physical properties of the tested sample;

3. Fast test speed: the average test time is about 15 minutes;

4. Wide range of application: It can measure various solid samples in powder, granule and block form and non-volatile liquid samples;

5. Wide test range: the density of samples is not limited;

6. Fully automatic operation: Embedded Windows CE operating system, touch screen control;

7. It can measure samples with different size ranges, the calibration data of each sample cell is automatically stored, and the data can be exported through the USB interface;

Application areas:

It can be used for production research in petrochemical industry, powder industry, new materials and other industries. Specific application materials can include: catalysts, filters, nuclear fuel, soil, fertilizers, carbon black, coke, fibers, minerals, pharmaceuticals, cosmetics, cement Quality control during the research and production of powders, foods, desiccants, powdered metals, ion exchange resins, silica gel, alumina, titanium dioxide, solid foams, and polymer materials.
