Jamar Hydraulic Hand Dynamometer

A standard in grip force measurement for more than 30 years, Jamar continues the tradition of accuracy and reliability with virtually leak-proof hydraulics. High quality, die-cast aluminum five-position handle easily adjusts to different grip spans ranging from 1-3/8” to 3-3/8”. Stainless steel gauge is protected by an exclusive shock-resistant rubber cap; wrist strap prevents accidental damage. Measures isometric grip force from 0-200 lbs. Includes instructions,  norms and a carrying/storage case.
