When pinpoint accuracy is thekey, the variety of featuresoffered in the PG70 andPG70DL allow users tomeasure with precision.The PG70 series have ThruPaint™ technologyallowing you to accurately measure the thickness ofthin substrates.The gauges are typically used for thin materialapplications. This gauge has the ability to calibrateto a variety of different materials using the one pointcalibration option.Some of the features include: High speed scan mode(allowing the user to scan an area for the minimumthickness), limit alarm mode enabling users to set theallowable thickness limits and differential mode whichdisplays the thickness variation (+/-) to a user definednominal thickness.
