Wooden Hand Steadiness Tester

HAND STEADINESS TESTER ELECTRICAL WITH IMPULSE COUNTER (ELECTRICAL SIMPLE ALSO AVAILABLE) • This test examines the steadiness of the hand and the fingers. • There is a box on one side of which there are some holes arranged systematically so that they proceed from the widest to the smallest. The subject takes an instrument called the stylus into his hand and inserts it completely and draws it out of these holes successively. • Whenever the stylus touches the walls of the hole, the impulse counter would indicate an error. • The Hand Steadiness Tester is also available without an impulse counter. In that case, whenever the stylus touches the walls of the hole, the light point would indicate an error. • Comes with a manual.
