This instrument is designed to test the opening and breaking torque of screwed closures and caps. It has good gripping power, peak hold capability, auto-calibration, and can measure in multiple units with a capacity of 50 kgcm and least count of 0.01 kgcm. Testing closure and opening torques is important for applications like automatic capping lines and designing suitable plastic cap threads to optimize performance and ensure proper closing without being too loose or requiring too much force to open.
