Description
B&L Hydraulic Hand Dynamometer measures grip strength from 0 to 200 lb at five handle positions for hand therapy and rehabilitation evaluations. Each unit ships with an official calibration certificate and an instruction manual with normative tables for adults and children.
- 0 to 200 lb Range – covers grip testing from early rehabilitation through full strength recovery
- Five Handle Positions – the adjustable handle fits different hand sizes and standardized test protocols
- Calibration Certificate Included – every unit is certified before it leaves the maker
- Normative Tables in the Manual – adult and child reference values are printed with the instructions
Grip Strength Measurement for Hand Evaluation
Hand therapists and rehabilitation teams use grip dynamometry to set a baseline at intake and to document progress across a plan of care. This hydraulic instrument reads force in pounds and kilograms on a dual scale dial, so results record cleanly in either unit. The handle adjusts to five positions, which supports standardized positioning for repeat testing and lets the clinician fit smaller or larger hands. Because the mechanism is hydraulic rather than electronic, there are no batteries to manage between patients. Each reading can be compared against the normative adult and child tables printed in the included manual.
Features and Benefits
Measurement Performance

Why Choose This Hydraulic Hand Dynamometer
Clinics keep returning to this instrument because its accuracy is documented unit by unit rather than promised in general terms. The certificate in the box reports the actual test results for the individual dynamometer, and the maker supports the line with factory calibration and repair.
- Documented Accuracy – the included certificate reports measured results for your exact unit, not a batch average
- Protocol Ready Out of the Box – normative tables and the five-position handle support standardized testing from the first patient
- Maker Support – the manufacturer offers calibration service and repair support for its instruments
Manuals and Troubleshooting Guides
Frequently Asked Questions
What does this dynamometer measure?
It measures grip strength from 0 to 200 lb, which is 0 to 90.91 kg on the kilogram scale. Therapists use the readings to baseline hand strength and to track recovery over time.
How many handle positions does it have?
The handle adjusts to five positions to fit different hand sizes. Using the same position at every visit keeps repeat measurements comparable across sessions.
Is a calibration certificate included?
Yes, an official calibration certificate ships with every unit. The maker documents a correlation coefficient of 0.9994 or higher and a mean deviation under 1.5 lb across its certification testing.
Are normative values included?
Yes, the instruction manual includes normative tables for adults and children. Those tables let the clinician compare a patient result against reference values for age and sex.
What warranty covers this instrument?
The manufacturer covers the instrument with a two-year warranty. The dynamometer also travels in a double-walled rigid case with fitted foam to protect it between uses.
