High resolution probes execute the conversion of coating thickness into an electrical signal which is in order to unveil the value of coating thickness on the display screen of device. Our high resolution probes have special cavity probe V3FGA06H designed for non-destructive measurements of EPD coatings ensuring high efficiency. These have patented conductivity compensation that enables adjustment for various base material conductivities. High resolution probes have spring-loaded system that ensures the decrement in calculation errors and thus helps in increasing the accuracy of the device.
