1、【Two Measuring Principles】Adopting principles of Magnetic Induction and Eddy Current Effect, it can measure the thickness of non-magnetic coatings on magnetic substrates such as iron/steel, and thickness of non-conductive coatings on non-magnetic substrates such as aluminum/copper/brass. 2、【Two Measuring Types】Feature Continuous Measuring Mode and Single Measuring Mode. Limit can be set and it will automatically sound an alarm when the measured value is outside the limit. 3、【Two Calibration Functions】Support both zero calibration and five-point calibration with 5 calibration films, offering you rapid and efficient calibration. 4、【High-sensitive Probe】Built-in integrated probe with high sensitivity, can automatically recognize basic material and test it quickly via one-button. 5、【Convenient Storage】Equipped with Type C interface, it can be connected to the computer easily for data transmission and sharing, more convenient to operate. 6、【Clear Display】Large backlit LCD display, shows everything clearly even in the darkness. Rotating screen design allows you to operate in a different direction. 7、【More Functions】Five statistics display, automatic shutdown, buzzing prompt, delete function, etc. 8、【Wide Application】Lightweight and portable body, can be widely used in painting, plating, automotive industry, aircraft manufacturing, porcelain magnetic and other industries.
