Functions & Features
- Display: LCD with LED backlight .The brightness and the contrast of the LCD is adjustable.
- Display contents: thickness value, coupling condition, power state, CAL calibration state, sound velocity.
- Able to measure the ultrasonic velocity in turn if the thickness value is known in order to improve the measurement precision.
- Zero adjustment: auto returning to zero when you press the key after the probe is put on the specimen.
- Simply and easily operated.
- Nonlinear correction, automatic compensation, in order to improve the measurement accuracy.
- The test block of measuring sound velocity of known thickness.
- Battery information indicates the rest capacity of the battery,Auto sleep and auto power off function to conserve battery life.
- Optional software to process the memory data on the PC.
- Alarm function: setting the measurement limit and alarming for the results beyond the limit.
Measuring Material
- Adapted to measure the thickness of good conductor for ultrasonic, such as metal(steel, cast iron, aluminum, copper), plastic, ceramic, glass, glass fiber and so on.
