Features PORTABLE AND RECHARGEABLE: Powered by a 3.7V lithium battery, this coating thickness gauge can be easily carried and recharged, providing continuous operation. NON DESTRUCTIVE INDUCTION: The car coating thickness gauge adopt two principles of electromagnetic induction and vortex induction to measure the thickness of the coating without destruction. MEASUREMENT OBJECT: Paint thickness gauge is used to measure the thickness of metal surface electroplating or coating. Used to measure the thickness of rubber, ceramic, enamel, paint, metal, and car paint. TWO MODES: The car coating thickness meter has two measurement modes to meet different requirements. The measurement data can be updated only once for a single measurement. Data is continuously updated during continuous measurement. APPLICABLE SCENARIO: Coating thickness gauge is professional for used car testing, iron, aluminum and zinc three uses, practical and useful.
