Product Description

PTG-3700 Coating Thickness / Paint Thickness Gage

The NEW! Phase II PTG-3700 coating thickness gauge/paint thickness gage is the latest state-of-the-art thickness gage.  This model can easily detect the thickness of non-magnetic coatings on magnetic(ferrous) substrates or an insulating coating on a non-magnetic conductive substrate(non-ferrous).  The PTG-3700 coating thickness gauge utilizes an integrated auto-detect probe, while the PTG-3750 coating thickness gauges uses an external probe.  The auto detect probes on these coating thickness gauges/paint thickness gauges use both eddy current and magnetic induction technologies.  The PTG-3700 series coating thickness gauges/paint thickness gauges are full featured w giant screen, backlighting, wider measuring range, advanced memory, browsing and statistics, such as min/max values, averaging and counters. The PTG-3700 coating thickness gauges/paint thickness gauges can be used in many areas of industry including mfg, general engineering, commercial inspection and automotive apps.
