Measure tip, key and palmer pinch strength in both pounds and kilograms. Measurements are accurate and repeatable. Results are consistent with published Markowitz studies. Indicator remains at the maximum reading until reset. Comes with or without protective case.
The Baseline® hydraulic pinch gauge uses the hydraulic system of the hand dynamometer to assure convenience, product reliability and measurement accuracy and repeatability. The therapist can support the pinch gauge during testing. This yields a more accurate result for all pinch tests including tip, key and palmer. The results are consistent with published Baseline® and Jamar® studies. Maximum reading remains until the unit is reset. The strength reading can be viewed as pounds or kilograms. Portable measuring unit comes with rugged carrying case. 1-year manufacturers warrantee. CE certified.

Mechanical Pinch Gauge – The finger pinch gauge can be used to measure pinch strength. It is calibrated in pounds and kilograms of force. Apply pinch force at the pinch groove while holding the pinch gauge between your thumb and finger(s). When force is applied further toward the tip the reading will be slightly higher. When force is applied further toward the rear the reading will be slightly lower.
Testing Protocol: Pinch Mechanical Pinch Gauges
The gauge must be “zeroed” before each pinch test. Grasp the knurled ring of the dial indicator and rotate it until the zero on the dial indicator is directly under the black pointer. The red maximum pointer must be reset before each pinch test. Rotate the small knurled knob on top of the dial indicator in a counterclockwise direction until it rests against the black pointer at the zero marking. The red maximum pointer will remain at the subject's maximum reading until it is reset. Use the pinch gauge to perform the three basic pinch tests: • Tip Pinch (thumb-index pulp pinch) - thumb tip to index fingertip • Key Pinch (lateral pinch) - thumb pad to lateral aspect of middle phalanx of index finger • Palmer Pinch (chuck pinch) - thumb pad to pads of the index and middle fingers NORMS FOR ADULT GRIP STRENGTH performance of all subjects (pounds)
