Wire crimp pull testers measure the pull-off force of crimped terminals.
WT3-201 manual wire pull tester and WT3-201M motorized wire pull testers are benchtop units that will test a majority of crimp types. They will test wire gauges AWG30 - AWG 3.
Motorized test stands and manual test stands can also be used for testing wire crimps. These would be a good choice if the force will be over 200 lbf and testing non-standard crimps and connectors. This will also provide flexibility with different types of crimps and connectors because the grips can be changed for the different crimps.
