Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.
Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification.
Ultrasonic transducers send and receive waves for many types of sensing. Examples include distance, proximity, level, nondestructive evaluation, web break detection, counting, and security applications.
