High quality tennis ball compression resistance tester must have the following functions
In the previous article, we have talked about《Parameter description of racket compression tester
》，So high quality tennis ball compression resistance tester should have which function？
We know,the instrument is designed to perform the compression resistance test of tennis ball. Conducting by the intelligent system, the tester defines qualified and unqualified balls. Users can modify specimen specification and parameter through the HMI system. During the test, the machine compress the sample. Meanwhile, it measures the maximum deformation of the ball. At the end, the deformation rate defines qualified and unqualified balls.
The machine has the following parameters recommended by Bang Instrument co.,ltd.
Range of Deformation:0.0～0.4in adjustable
Displacement Accuracy:0.001mm
Test Speed:one times/min.
Preliminary Force:3LB
Compression Force of Deformation:18LB
Power 1∮,AC 220V,50/60Hz (specified by customer)
