The TSP-jr Almen Gage is a precision device used for measuring the deflection or curvature of a metal test coupon called an Almen strip. It is fitted with a calibrated high accuracy analog indicator with a low-force spindle spring to provide highly accurate and repeatable measurements.
Treated properly, this gage will give many years of trouble-free service. A flat â€œCheck Blockâ€ is supplied with each gage to allow the owner to set the zero datum. The gage should be recalibrated (both indicator performance and ball wear) annually or more frequently if conditions warrant.
The analog indicator has a resolution of 0.0005 inch.
