The digital surface profile gauge will allow the peak to valley height of blast cleaned surfaces to be accurately measured in accordance with the ASTM standard. Caltech’s digital surface profile gauge is highly useful and users friendly tool for paint, coating, and corrosion inspection.
gauge is initially set to zero with the glass zero 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 measurement 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. Instrument is supplied with calibration certificate traceable to national standards. Surface Profile Gauges are also known as Needle Gauge.
Supplied in Carrying Case with Glass Zero Plate, Alen Key, and Battery fitted.
An Analogue Surface Profile Gauge is also available.
