The TSP-3 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 electronic digital 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 curved â€œCheck Blockâ€ is supplied with each gage to allow the owner to check the condition of the gage weekly. The gage should be re-calibrated (both indicator performance and ball wear) annually or more frequently if conditions warrant. The gage comes with 2 batteries installed and an expected battery life of greater than one year. The batteries are easily replaced without loss of calibration.
The digital indicator has an accuracy exceeding 0.005 mm (over a range of 0 â€“ 0.600mm).
