Purchase of pressure testing machine

The compressive strength of materials in different industries is different, so the measuring range of pressure testing machines is also different. Although the testing range is downward compatible with the maximum test force as the upper limit, it is difficult to ensure the accuracy of the test results by using a large range of equipment to test samples with low compression requirements. Therefore, all testing machine manufacturers will mark the measuring range of force value on the technical indicators, such as the range of 4% - 100% F.S. The correct way to select and purchase the pressure testing machine is to find out the model and scope of application of the pressure testing machine from the manufacturer according to the material and specification of the sample, or provide the sample to the manufacturer for a test to facilitate the selection of the pressure testing machine.
