Working Principle

　　Determine the force required to produce a specified indentation under specified conditions. Place the specimen between the upper and lower platens, then apply compression at a specified speed. When the upper platen compresses the specimen downward, the load cell mounted on top of the upper platen detects pressure, converts it into a voltage signal and transmits it to the display unit for analysis, meanwhile showing the pressure value on the display.
