Product Introduction
KD-Cpad VX series: Special for cast iron spheroidization rate detection
The KD-Cpad VX series ultrasonic acoustic velocity meter brings lossless measurement spheroidization rate to the extreme; it provides fast ultrasonic rate detection to determine the spheroidization rate of safety components such as automobiles.
At the same time, reliability, performance and durability areall your most trusted and hardworking partner, no matter where you inspect it. This innovative spheroidizing meter will provide users with an extraordinary experience. In the case of a comparison test block, it is also suitable for creeping rate measurement.
Suitable for measuring the spheroidization rate (creeping rate) of cast iron materials, complying with JB/T9219 standards; it is also suitable for measuring the sound speed of metals, plastics, ceramics, glass, fiberglass and any other ultrasonic conductors.
Product Function
Lossless spheroidization rate measurement
The relationship between ultrasound and spheroidization rate is used to perform damage-free spheroidization rate measurement; by accumulating a large amount of experimental data, the spheroidization rate algorithm is optimized to improve measurement accuracy.
Thickness measurement of penetrating coating
The powerful penetrating coating thickness measurement function eliminates the tedious preparation work of hard polishing, and can measure thickness easilyby simply treating the coating surface slightly.
No standard test block required, automatic calibration of zero point probe
Advanced probe zero point real-time automatic calibration technology to track the world's latest technology trends. It eliminates the trouble of manually calibrating the zero point of the probe, and also solves the measurement error caused by the zero point drift of the probe, ensures accurate measurement values, and get rid of the dependence on standard test blocks.

Measurement interface (spherization rate 100%, level 1)
USB drive storage, plug and play
USB port can be plugged into a USB disk, no driver required, plug and play, and thickness reporting is achieved
100,000 measured values and ultra-large capacity data storage
Data statistics
Online statistics during the measurement process: maximum, minimum, standard deviation; data file statistics: maximum/minimum, mean, mean square deviation
Probe connection status indication/coupling status judgment
It has the function of indicating the connection status of the probe; the coupling strength of the signal is indicated; the measured value shows the change of solid/hollow, and it is intuitively indicating whether the coupling condition can be measured normally.
