Product Description

12-539-3 Standard Test Block: 85-95RB

The 12-539-3 has approximate sizes of: 1-1/2″ L x 2-1/2 W x 1/2″ H.

Features:

Standard test blocks provide an easy means of checking your tester’s accuracy.

Periodic testing on a regular basis is recommended.

Comparing a test reading of the block with the hardness number on the test block will indicate whether or not the instrument needs attention.

A surface rating of less than 5 micro-inches (CLA), indicates that both test and supporting surfaces are flat and parallel prior to being calibrated.

Order the hardness range and scale which is approximately the same as the work you will be testing.
