    Built-In Probe

    These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Use them to measure coatings such as paint, galvanizing, plating, and enamel. They display readings in mils and microns; for readings in mils, one mil equals 0.001". All have a wear-resistant ruby probe.

    Coating-Thickness Gauge Inspection Kits

    Image of Product. Front orientation. Thickness Gauges. Coating-Thickness Gauge Inspection Kits.
    With three included probes, the gauge in these kits goes beyond a typical check for coating thickness. It also measures surface profile and environmental conditions, such as temperature. Kits include everything you need for thorough tests whether you’re inspecting a surface that’s painted, powdered, or plated. Just swap out probes to measure what you need. Use the plate and shims to practice measurements and ensure the probe is working properly. The glass plate and metal shims work with the surface profile probe. The plastic shims work with the coating thickness probe. Easy to use, the gauge’s touch screen guides you through measurements step-by-step.
    Switch between scan modes for full control over how you measure, from single-point tests to continuous readings. You can even find stats and create presets for repeated measurements. For long-term tracking, the gauge stores up to 250,000 results from multiple probes in up to 1,000 batches. See trends in real time with live graphing. To help you comply with ISO, ASTM, SSPC-PA, and IMO coating standards, set criteria for go/no-go tests.
    Thanks to a compatible app, you can add notes and images to readings or make reports on the go. For exporting into programs such as Excel or making multimedia reports in templates, use the included software.
    Choose kits based on coating and surface types.
    Built-In Probe—A built-in probe lets you use the gauge one-handed—no extended probe to maneuver.
    Removable Probe with 3 ft. Cable—A removable probe means you can measure underwater and up to 3 ft. away. The waterproof probes are at the end of sealed cable, so you can reach surfaces without submerging the gauge.
    For Nonconductive Coatings—Kits with probes for both nonconductive and nonmagnetic coatings include a thickness probe that automatically identifies the coating and surface material.
    For 0 mil to 250 mil Thick Coating—Kits with probes for 0-250 mil coating thickness are ideal for testing epoxies, flame-retardant finishes, and other thick coatings.
