Thickness gauges(ultra-sonic)

Application: Accurately measuring remaining wall thickness of metal pipes, tanks, beams, ship hulls, and other structures through paint and similar coatings.

Background: In many industrial and petrochemical maintenance situations it is necessary to measure the remaining thickness of metal that is subject to corrosion through one or more coats of paint or similar non-metallic coatings. With conventional ultrasonic thickness gages, the presence of paint or similar coatings will cause measurement errors, typically increasing the apparent metal thickness by more than twice the thickness of the paint, due to the paint's much slower sound velocity. Two solutions to this problem are available: echo-to-echo measurement and Thru-Coat measurement.

Specifications H cross hatch cutter is applicable to determine the adhesion of organic coatings by cross-hatching. This instrument is designed for assessing the resistance of paint or related coatings to separation from substrates when a right-angle lattice oattern is cut into the coating, penetrating through to the substrate. The Cross Hatch Cutters conform with the requirements of :BS 3900 E6;BS/EN ISO 2409;ASTM D 3359;GB/T 9286, ,it is economy. Main Technical Parameters: 1.Six working side blades:When the blade edge is not sharp enough, users can loosen the boat type nut and top thrust screw to change blade. 2.Multi-cutting blades spacing:1mm/2mm/3mm 3.The number of square:25squares/100squares
