Coating Thickness Gauge CM-8828 1.Spec: The F probes measure the thickness of non-magnetic materials on magnetic materials. The NF probes measure the thickness of non-conductive coatings on non-magnetic metals. 2.Features: * Two measuring methods: magnetic induction (F) and eddy current (N) * Two measurement mode: Single and Continuous（Notice：Continuous mode is convenient to measure the coating thickness of curved objects and tiny objects.） * Metric/imperial system selectable. * Manual or automatic shut down. * Automatic memory of calibration value,and automatic recognize the substrate. * Operation process have buzzing reminder,while no buzzing in continuous mode. * Use USB/RS-232 data output to connect with PC. * Provide Bluetooth data output choice. * One key operation, fast and convenient. 3.Specifications: Principle: NF Type Eddy Current & F Magnetic Induction Range: 0~1250µm/0~50mil Resolution: 0.1µm/1µm Accuracy: ±1~3%n or ±2.5µm Min.
