CombGauge is a field calculator designed for industrial spray coaters, marine painters, and protective coating inspectors who need fast, accurate film thickness verification on the job. Applying coatings without real-time thickness validation risks costly failures including runs, sags, mud cracking, and solvent entrapment. CombGauge converts raw notched wet-film comb measurements directly into specified Dry Film Thickness (DFT) while accounting for solvent evaporation, thinner cut percentages, and surface roughness absorption. BUILT FOR INDUSTRIAL FIELD CONDITIONS • 100% Offline Capability: Operates entirely without cellular reception or Wi-Fi, making it reliable inside ballast tanks, ship hulls, fabrication yards, and blast booths. • No Accounts or Cloud Sync: Instant access with zero sign-in barriers, trackers, or background data consumption. • Bidirectional Calculations: Determine target Wet Film Thickness (WFT) from specified DFT, or calculate predicted cured DFT from a live comb reading. • Thinner Dilution Compensation: Adjust calculations accurately for reduction percentages added during field mixing. • Surface Profile Correction: Factor in blast profile anchor patterns and substrate absorption to prevent dry spray and under-thickness non-conformance. • Dual Unit Support: Switch seamlessly between metric (microns/µm) and imperial (mils) measurement systems. CombGauge delivers practical, accurate coating calculations directly to field operators, supporting quality control compliance and reducing rework across structural steel, marine, and industrial maintenance projects.
