This machine is used to test material compressed indentation hardness, such as: sponge, foam .the basic principle is that we put the sample under the pressure plate, then the pressure plate start to compress the sample , when the concavity get to the Set value(according to the national standard requirements), the load sensor will feedback the pressure to computer, then the computer will clearly show the indentation hardness. We can save and print the date.
the national standard requirements of the A method, B method, C method of the standard size of the sponge, foam and other samples of the standard test, Measured sponge, foam and other materials, the pressure of depression. The instrument for the computer control, the test process can be a variety of data quickly and accurately collection, processing, and access, display, print.
Apply to GB/T10807-89,ISO 2439-1980 Requirements
1.the testing speed of pressure plate: 10-500mm/min;
2. compressed indentation hardness range:100KG
3.the deviation: less than 1%
4.the pressure plat diameter: 200 mm
5.the bottom fillet:R1 mm
6. Units: Kg, N, Lb
Set the concavity value in advance, the timing circuit will accurately control it.With high-precision pressure sensors and large scale integrated circuits. it is easy to controlThere are three methods(A,B,C)to test the indentation hardnessThe system automatically clears the system after receiving the starting command.When the specimen is breaking, it will returns to the original position.According to the size of the load, it can switch the different gears, to ensure measurement accuracy is goodAdjustable testing speed according to different samplesCalibration The computer will display Data and curve testing dynamic process. then we can know and analyze the date of every pointsThe data curve test result can be read and storeWe can adjust test speed, displacement, strain and other test methods according different requirementWe can use different kind of sensors in one testing machine, it can be used widely.It will Automatically shuts down when the load exceeds the rated value.
