Oxford 700 Series Copper Thickness Measuring Instrument CMI700

Product Features:

1. Integrated measurement of the thickness of hole copper and surface copper, convenient and cost-effective
2. Two methods, micro resistance and eddy current, are used to accurately measure the thickness of surface copper and hole copper
3. The measurement system has high versatility and scalability, and its compatibility with multiple probes meets various application requirements, including surface copper, hole copper. At the same time, CMI700 has advanced statistical functions for organizing and analyzing test data.
4. The SRP-4 series probes apply advanced micro resistance testing technology. When measuring, the thickness value can be accurately and reliably obtained by the function relationship between the thickness value and the resistance value, without being affected by the thickness of the insulation board layer or the copper layer on the back of the printed circuit board. The SRP-4 probe, which can be replaced by users themselves, is a patented product of Oxford Instruments. The lost probe can be quickly and easily replaced on site, reducing downtime. Replacing the probe module is far more economical than replacing the entire probe.
