Analogue Surface Profile Gauge
The Analog Surface Profile Gauge will allow the peak to valley height of blast-cleaned surfaces to be accurately measured in accordance with the ASTM D-4417 Method B standard. The gauge is important tool in assessment of degree surface preparation or surface cleanliness before painting.
The gauge is initially set to zero with the glass zero plate. The needle touches the glass plate and the foot is then placed on the blasted profile. The foot sits on top of the peaks and the sharp stylus travels to the bottom of the valley, allowing the gauge to display the peak to valley height. A number of measurements can be made and the average taken.
In addition the gauge can also be used to measure the effects of corrosion, i.e. pitting and cavity depth etc.
Supplied in Carrying Case with Glass Zero Plate.
