Temperature gauge

"GUOOU" (USA Technology) Assembled in China highly intelligent and precise Paint Coating Thickness Gauge used to quickly & accurately measures the thickness of coating & planting on almost all kind of metal surfaces. It not only indicates thickness of coating or planting but also automatically identifies the base material. It is applicable to measure non magnetic painting, ceramic, enamel, plastic, rubber coating on magnetic base materials such as iron & steel, non ferrous metal planting such as nickel & chromium, anti corrosive coating, non conductive painting, plastic coating and anodic oxide film on non magnetic conductive devices. FUNCTIONS Measuring: Contentious & single measurement available Memory: 600 Data Store Unit: Metric/Imperial switchable (mil/um selectable) Calibration: Zero-in, 2 point Calibration and multi point calibration selectable Battery: Low Battery Indication Data Transfer: Bluetooth or USB APP: Mobile App (Play store) Window, Android App, IOS App Data Delete: Delete a single Data or all data function available SPECIFICATION Range: 0-1500 um/ 0-60 mil Resolution: 0.1 um / mil Accuracy: ± (1+2%um) Minimum Test Surface: ? 10mm Minimum Thickness of Base Material: 0.4mm Temperature: -10 Deg. C to +50 Deg. C
