The digital handheld compression force measurement tool is a small, simple, multi-function, and high-precision push and pull test measurement instrument, which is widely used in electronic appliances, construction hardware, fire equipment, power machinery, scientific research institutions, and other industries. Like the digital force gauge push pull tester, the handheld force gauge for springs has a high resolution, fast sampling speed, and is easy to read. And this compression force gauge or sensor is a new high-precision push-pull test instrument.
