■ Measure peak-to-valley height of blast cleaned surface.
If the profile is too low, the adhesion of the coating to the surface will be reduced.
If the profile is too high, there is the danger that the profile peaks will remain
non-coating, maybe rust spots happen. ■ Meet ASTM D 4417-B ■ Zero set block is included, set zero before measurement ■ Buttons: tolerance Go and No-Go display, data preset, measuring direction change, max./min./TIR measurement, inch/metric conversion, absolute/incremental measurement ■ CR2032 battery, automatically power off ■ Data output (cable code:200-03 or 200-04) ■ Stainless steel base
