SH-69
Measuring Induction-Hardened Layer Depth Without Cutting the Product
The SH-69 is a device for nondestructive measurement of induction-hardened layer depth.
By using the SH-69, conventional processes such as cutting the product, etching, and depth measurement can be eliminated, improving operational efficiency.
The SH-69 is an innovative device that uses ultrasonic waves to detect differences in grain structure between the induction-hardened surface layer and the base material from scattered echoes. It nondestructively measures the depth of the induction-hardened layer and digitally displays the measurement result.
By selecting the optimal probe and setting the measurement conditions according to the measurement location, the boundary between the induction-hardened layer and the base material can be identified, enabling accurate and stable measurements.
The SH series is widely used for measuring induction-hardened layer depth in components for automobiles, wind power equipment, construction machinery, agricultural machinery, ships and marine equipment, internal combustion engines, machine tools, and various other industrial components.
The SH-69 retains the functionality of the previous SH-67 model while incorporating a 7-inch widescreen LCD touch panel for improved ease of operation and visibility of measurement results. It also features new pass/fail judgment and correction functions.
The following are our key advantages.

Measurement Principle and Features
The SH-69 employs ultrasonic waves to measure the depth of the induction-hardened layer. In the hardened layer, the microstructure is refined by hardening, so ultrasonic waves pass through it easily and the scattered echo is weak. In the base material, by contrast, the microstructure is coarse, so ultrasonic scattering occurs readily, and the scattered echo is strong. By detecting the position where the scattered echo becomes strong, the SH-69 determines the boundary position between the hardened layer and the base material.
