Eddy eddy current thickness ED300 coating thickness gauge thickness meter I. Overview This gauge is a portable, non-destructive, rapid and accurate measurement of precision instrument coating thickness. Widely used in anti-corrosion, electroplating, chemical, automotive, shipbuilding, aviation, light industry, for laboratories, factories and outdoor field use. In line with GB / T4957-2003 standards. According to the principle of magnetic induction magnetic thickness, no damage can be detected magnetic metal substrates (such as: iron, steel, alloy and hard magnetic steel, etc.) on a non-magnetic coating thickness (for example: zinc, aluminum, chromium, copper, paint, Lang, rubber, paint, etc.). Eddy current thickness according to the eddy current principle, can be no damage to detect non-magnetic metal substrates (such as aluminum, copper, zinc, tin, etc.) on the thickness of the non-conductive coating (such as paint, anodized film, ceramics, plastics, rubber, etc.) . Second, the standard configuration Standard configuration: two hosts, probe, zero plate, standard foil, 5 # batteries, operating manual, certificate warranty card. Third, Features 1. portable design, palm-sized. 2. The user-friendly design, simple operation. 3. The wide-angle LCD display. 4. Operation procedure has Beeper. 5. With automatic shutdown function (90 seconds can be set off, can also choose non-automatic shutdown). 6. converting metric and imperial units. 7. With supply undervoltage tips. 8. The statistical functions: number of measurements, mean, standard deviation, maximum, minimum. 9. accurate measurement on the probe end of the pin V-groove ensures convex.
