Product Overview

Description

(The G-type Standard Test Blocks (STB) are a series of test blocks containing flat-bottom holes and are used in straight beam (normal) testing. They are used to adjust the working sensitivity, to measure the characteristics of the normal beam probe, and to measure the overall performance characteristics of the ultrasonic test equipment. All versions are offered, including the STB-G V2, V3, V5, V8, and six V15 blocks. Each block contains a unique metal-travel distance, flat-bottom hole diameter, and overall block size.)
