This instrument is a hydraulic machine. Select the compression strength, tensile strength, shear strength or transverse testing program from the digital display instrument. Turn the hand wheel to make a pressure through a piston in the machine. A horizontally moving arm applies pressure on a sand specimen until it collapses. Read the strength value from the led display. Feature: 1. The strength is tested by hand-driven the wheel. 2. The strength machine is capable of running the following different sand strength tests:compression strength, shear strength, tensile strength, and transverse strength) with additional fixtures and accessories which is easy to connect to the machine. 3. Select the testing program from the digital display instrument. 4.The testing strength value is read from the led display. Size:650x350x250mm Weight:40kgs
