Dry film thickness by ultrasonication meter
- 1. PosiTector 200 Non destructive thickness measurement Gage Significance and Precision
- 2. PosiTector 200-Introduction PosiTector 200 used for Non destructive thickness measurement of one or more layered dry surfaces in microns /Mils. This Instrument work on Ultrasonic waves due to variation in density on interfaces. The standard test method is described in ASTM D6132-04. “Standard Test Method for Nondestructive Measurement of Dry Film Thickness of Applied Organic Coatings Using an Ultrasonic Gage” (2004, ASTM).
- 3. Dual Layer Measurement Graphics option of Instrument accessed using the “Set Range” menu. Narrow and high peaks denotes major change in density and uniform Wide and low peaks indicate –Blended/Composite materials where density is gradually change Positector 200 use highest peaks as a thickness results in selected range in case of multilayer it uses two or three higher peaks for out put. The nature of composition of a composite can be understood easily by Graphical representation.
