Unlike conventional pinch gauges, the Jamar Hydraulic Pinch Gauge's unique design frees the client to perform a true pinch pattern because the therapist, not the client, supports the weight of the gauge. A highly accurate pinch-force measurement, devoid of artifact, is the result. Red indicator remains at maximum reading until reset. Measures pinch force up to 45 lbs. Includes instructions, and handy carrying case.
