GoodsBazaar 0.01 mm Checking Blasting, Paint, Coating and Corrosion Digital Surface Profile Gauge Portable Surface Roughness Tester Needle Gauge Digital Caliper  (0-1000 Microns mm)

This Digital Surface Profile Gauge is a handheld gauge for fast and accurate measurement of the peak-to-valley height of the surface profile of blast-cleaned surfaces. It meets the standards of ASTM D 4417-B, IMO MSC.215 (82), SANS 5772, US Navy NSI 009-32, US Navy PPI 63101-000. Suitable for the laboratory and for use in harsh field conditions. Accurate, immediate and repeatable results. The tungsten carbide tip will last for up to 20,000 readings and can then be easily replaced by the user in the field. Cost per test is significantly lower than other test methods. Used the exclusive Micro -computer LSI circuit and crystal time base to offer high accuracy measurement. Can communicate with PC. Automatic power off to conserve power. Widely used in field of blast cleaned surface measurement. If the profile is too large, the amount of coating required to ensure adequate coverage increases, otherwise there is a danger that the peaks remain uncoated - allowing rust spots to occur. If the profile is too small, there may be an insufficient key to produce adequate adhesion, leading to premature coating failure. Ensuring the correct surface preparation optimizes the performance of the coating and material usage. Applications: Enables quick assessment of surface condition prior to coating. It works on grit sand shot blasted and saw cut surfaces. The small size of this surface profile gauge makes it easy to use and easy to balance on the surface. Its design permits accuracies equivalent to an electronic surface trace. Gives maximum peak to average valley height. Available with metric and imperial units. This gauge can also measure the depth of pits, cracks, craters and scratches of the outer (and in some cases the inside) surfaces of steel structures, pipes and concrete. Optional software for data output.
