The TPG triple path glass calibration test block is used for the zero calibration of ultrasonic bolt tension meters. This calibration test block is easy to use, very precise and resistent agaist temperature changes. The latter is attributed to the fact that the TPG is composed of the same glass material that is used in the aerospace industry.
The TPG glass calibration block has 3 testing paths: 1", 2" und 3" (25,4 mm, 50,8 mm, 76,2 mm).
This precision made Triple Path Glass Calibration Block is delivered witha a NIST traceable calibration certificate in a foam fitted hard plastic carrying case.
