Positector SPG - Surface Profile Gauge
The PosiTector SPG Surface Profile gauges measure and record peak to valley surface profile heights. A durable Alumina wear plate and tungsten carbide needle probe replaces the dial gauge specified in the Australian standard allowing quick data logging of the surface profile of blasted steel or textured coatings.
The Surface Profile gauge is on of the standard probes include with a PosiTector Inspection Kit.
Conforms to AS 3894.5-C (with optional 30° tip angle), ASTM D4417-B, SSPC-PA17, U.S. Navy NSI 009-32, SANS 5772 and others.
Theory
Surface profile gauges are used to record the surface profiles on blasted or otherwise prepared metals before coatings are applied. The PosiTector uses method C - Needle-Type Depth Micrometre from the Australian Standard AS 3894.5-C.
A depth measuring probe with a 30 degree angle needle, tip radius 20 μm is set to a zero from an undamaged plate glass surface. Multiple measurements are taken, low readings discarded and the mean used as one test area. The average profile height is then recorded.
How to select your probes
For testing blasted steel or other metal an SPG or SPG S along with an accessory 30 degree tip probe is suitable for testing in Australia, an SPG OS is useful for testing over convex surfaces with the same 30 degree tip. The SPG CS probe has a greater measuring range but is suitable only for measuring textured coatings.
