Unique Solutions for Clinical And Research Applications - Biometrics Ltd
MyoMeter, Pinchmeter & Hand Dynamometer
Biometrics Ltd manufacture a range of precision load cell based devices to connect to the DataLOG, DataLINK, and K800. Multiple devices may be used simultaneously - for example two dynamometers for simultaneous bilateral dynamic grip strength testing.
The MyoMeter, Pinchmeter and Dynamometer connect to Biometrics Ltd instrumentation – DataLOG, DataLINK, or K800 - using the H2000 cable. The output from the devices can readily be combined with EMG, joint goniometry movement data, or other sensor inputs into one simple system.
The Biometrics Ltd MyoMeter, Pinchmeter and Dynamometer can also be connected to various 3rd party instrumentation. Please contact us for full technical information.
Myometer M550
The M550 allows the user to quantify the force applied during Manual Muscle Testing. Manual Muscle Testing is a procedure for the evaluation of the function and strength of individual muscles and muscle groups based on effective performance of a movement in relation to the forces of gravity and manual resistance.
The M550 MyoMeter is held by the examiner with the curved anvil placed against the body part to be tested.
The limb is stabilized and held in the desired starting position. The patient is instructed to
hold the limb in position and resist the force applied by the examiner. The examiner applies force
gradually until the limb is depressed. The force required to move the limb is referred to as the
“breaking force”.
| Dimensions | 115 x 65 x 32 mm |
| Mass | 250 g |
| Accuracy | Better than 1% Rated Load |
| Rated Load | 0 to 500N, Calibrated and designed to work in compression only) |
| Anvils | 1 small, 1 large |
| Cable | Direct connection to DataLOG, DataLINK and K800 using cable type no. H2000 |
The M550 MyoMeter is supplied with two anvils:
1 x general purpose (small)
1 x general purpose (large)
By connecting the M550 MyoMeter to the DataLOG or the DataLINK and using the management & analysis
software, force may be displayed and analysed in units of Newtons, Kg or lb. The M550 may also be
connected to the general purpose amplifier K800
for direct connection to 3rd party instruments
such as A/D cards
Precision Dynamometer G200
The Biometrics Dynamometer utilises precision load cell technology to increase the sensitivity and accuracy of measurement of even very low grip strength forces. By using the industry standard Jamar design exterior researchers can compare with standardised normative data. Total accuracy is better than ± 1%. Full scale 0-90Kg or 0-200lbs.
| Dimensions | Standard Jamar configuration, calibrated and designed to work in compression only |
| Mass | 630 g |
| Accuracy | Better than 1% Rated Load |
| Rated Load | 0 to 90 Kg or 0 to 200 lb |
| Cable | Direct connection to DataLOG, DataLINK and K800 using cable type no. H2000 |
Precision Pinchmeter P200
| Dimensions | diameter 45 X 6 mm |
| Mass | 65 g |
| Accuracy | Better than 0.6% Rated Load |
| Rated Load | 0 to 22.5 Kg or 0 to 50 lb |
| Cable | Direct connection to DataLOG, DataLINK and K800 using cable type no. H2000 |
The unique electronic pinchmeter has a low profile design that enables the researcher to accurately
quantify pinch strength at closer to end range than any other device. The total accuracy is
better than 1%. Full scale 0-20Kg or 0-50lbs.
