Peel Testers

Calculate how hard it is to peel tape off a surface, separate the layers within a laminate, or unfasten a hook and loop. These testers are often used for prototyping and quality control with packaging and electronics to check the bond strength between two materials. To test, stick your sample onto the testing tray and secure one end of it to the force gauge above. The tray moves as the force gauge pulls your sample up, so the sample is always peeling at a 90° angle. Program your test settings on the display. You can start or stop the test manually, set it to run for a certain amount of time, or let the test run until your sample is completely peeled off. All testers meet ASTM standards for peel testing.

Use the USB cord to transfer data and view measurements with the included computer software. The software identifies the first peak, or the maximum force recorded when your material first starts to peel. It also generates graphs and makes it possible to export data into a CSV file.

Cannot Be Sold To—Testers cannot be sold to the listed areas due to energy efficiency requirements.

Digital Coating-Thickness Gauges with Certificate of Calibration


Removable Probe with 3 ft. Cable	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 Gauges for Hard-to-Reach Areas

These pen-shaped gauges are good for use on hard-to-reach surfaces. Use them to measure nonmagnetic coatings such as paint, galvanizing, plating, and enamel on steel. These gauges display readings in mils and microns. For readings in mils, one mil equals 0.001". They come with a calibration certificate traceable to NIST that states they have passed a test for accuracy.

Scratch-Resistance Hardness Testers

Determine the relative hardness of resins, film, lacquer, and paint by testing their resistance to scratches by graphite pencils. The pencils are calibrated to specific lead grades for hardness. The lowest hardness value of the pencil that mars the material is the material’s relative hardness. Flatten the tip of the pencil lead with the included 400 grit sandpaper, then insert the pencil into the tester. As you push the tester over your material, the pencil is dragged across the surface at a constant pressure. These testers are often used in the development of synthetic resins. They meet ASTM D3363 for testing the hardness of coatings.

Coating-Thickness Gauges

Use these gauges to measure nonmagnetic coatings such as paint, galvanizing, plating, and enamel on steel. All come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Hold the probe on your material for a quick reading. These gauges display readings in mils; one mil equals 0.001". They have a wear-resistant carbide probe and a go/no-go button for rapid measurement. A V-groove in the base provides stability on curved surfaces.

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.
