2-Point TesterChristy ManufacturingPleasanton, California 2002 Designed to test touch sensitivity, the Christy 2-Point tester is a revolutionary design improvement over current touch test products. The Christy design uses two rotating disks that precisely set the distance between the test points. In all, 16 different point gaps can be created with this one disk. Traditional designs that use steel pins embedded in a plastic disk are vulnerable to damage if dropped and require the doctor to carry 2 disks to get the same 16 points provided for in the Christy design. |
