Red indicator remains at maximum reading until reset. A highly accurate pinch-force measurement, devoid of artifact, is the result. Measures pinch force up to 45 lbs. Includes instructions and handy carrying case. Warranty: 2-year warranty. Rubber gauge cap contains latex. Caution: This product contains natural rubber latex which may cause allergic reactions.
