What is the sound speed range of HCH-3000E ultrasonic thickness gauge for science and trade?

HCH-3000E ultrasonic thickness gauge can be printed and communicated with PC, and the measurement report can be directly sent to printer for output or transmitted to computer for display, which is very good. Sound speed range: 1000-9999m/s, and the sound speed of 10 kinds of common materials is built in the instrument for users to choose directly; Back measurement of sound velocity: According to the known thickness of the material, the sound velocity of the material can be back measured.
