A force gauge is a measuring instrument that measures various forces such as tensile force, compressive force, and pressing force. It is also called a push-pull gauge or push-pull scale. It is used as a measuring instrument for compression / tensile tests, and for measuring friction, peeling forces and the strength and durability of materials using attachments. There are various types such as digital force gauges and small benchtop test machines. A digital force gauge manages data by connecting to a computer. It measures from 20.0 to 500.0 N and can be switched to kg or g as well as N. A compact benchtop tester is a measuring instrument that includes a digital force gauge, an electric stand and dedicated software. By connecting to the USB port of the PC, operations such as turning on and off can be performed from the PC.
