This coating thickness tester has LCD display with backlight, easy to read values. Two measurement modes design, with single point measurement mode and continuous measurement mode for you to adjust. Support upper and lower Limit value locking, custom calibration, high alarm and low alarm function, data clearing, m/mil unit conversion, automatic switch-off for approx. 10 minutes without operation. Support detect steel, iron, copper, aluminium, alloys, etc. And also can detect the thickness of non-conductive coating (such as paint, oxide film, plastics, ceramic) on the surface of metal materials. Features: LCD Digital Display: LCD backlit display with clear definition, no fear of day and night, no fear of summer and winter temperature changes, and easy to read values. Single Point Mode: Quickly press the probe vertically against the surface of the substrate to be measured, a beep will sound and the measurement value will be displayed on the screen, the probe should leave the surface of the substrate for more than 50mm before another measurement, the measurement interval is 2 seconds. Rapid Continuous Measurement Mode: The instrument is held in the hand and the probe is quickly pressed vertically against the surface of the substrate to be measured, the measurement value is displayed on the screen, the measurement point can be changed at will or slid on the surface of the substrate to quickly complete continuous measurement. Composite Probe: Suitable for Fe magnetic materials, NFe nonmagnetic materials. v-groove, for measuring convex curved surfaces such as the surface of steel pipes. Upper and Lower Limit Value Locking: When the measurement status screen shows a number, short press MAX/MIN to change the desired upper and lower limit value locking function, multiple measurements on the substrate surface will lock the upper and lower limit value of the measurement. Custom Calibration: Place the standard 50m/100m/250m/500m/1000m individually on the surface of the iron or aluminium substrate, the corresponding calibration point should be displayed when the instrument probe is in contact, if the screen shows a large error with the placed standard, press CAL in the same way as zero-calibration. Alarm Function: With high alarm and low alarm function, high 1500m, low 0m default alarm value, support alarm setting mode, easy to adjust the alarm value size, can set any alarm thickness value. Multi-functional Design: Data clearing, m/mil unit conversion, automatic switch-off for approx. 10 minutes without operation. Applicable Materials: This instrument is a necessary measurement tool for material surface treatments projects, and can detect steel, iron, copper, aluminium, alloys, etc. And also can detect the thickness of non-conductive coating (such as paint, oxide film, plastics, ceramic) on the surface of metal materials. Wide Applications: It can be widely used in automotive manufacturing, metal processing, industrial manufacturing, used car market, etc. Specifications: Name: Coating Thickness Tester Material: plastics+metal Battery: 2 * 1.5V AAA battery Measuring ranges: 0-1500m Automatic switch-off: approx. 10 minutes Measuring method: single/continuous Min. convex radius of curvature: 5 mm Min. concave radius of curvature: 50 mm Min. measuring area diameter: 20mm Minimum substrate thickness: iron based 0.5mm/aluminium based 0.3mm Operating current: approx. 30mA Working environment: 0~50C/0 ~ 80%RH Item size: 120 * 48 * 26mm / 4.72 * 1.89 * 1.02in Item weight: 95g / 3.35ounce Package size: 160 * 80 * 70mm / 6.30 * 3.15 * 2.76in Package weight: 200g / 7.05ounce Packing List: 1 * Coating Thickness Tester 1 * Lanyard 1 * Screwdriver 1 * Flannel Bag 1 * Standard Sheet 1 * Manual
