    How To

    • Hold the plastic handle firmly and bring the probe tip to the seam you want to inspect.
    • Position the probe so the blunted 90° tip lightly contacts the membrane seam.
    • Slide the probe along the seam to detect voids, cold welds, or defects.
    • If extended reach is needed, screw on a 60″ extension pole to the threaded handle and continue testing.
    • After inspection, wipe the probe clean and retract from tight areas.
    • Check the handle’s threads or extension connection for debris before reuse.
    • Store the tester in a dry place to protect the probe and handle.

    FAQs

    Q: What does the MM21060 do?
    A: It’s a seam tester for verifying single-ply membrane welds (TPO, PVC, EPDM). The 90° blunted probe helps detect voids and cold welds without gouging the membrane.

    Q: What makes it “convertible”?
    A: The threaded handle accepts Everhard’s 60″ fiberglass extension handle (MR02400) for stand-up testing, or it can be used as a handheld probe for detail work.

    Q: What are the size and weight?
    A: Overall length is about 10.25″; the probe is roughly 5″ long. The tool weighs about 0.16 lb, making it lightweight for all-day use.

    Q: Any usage tips for best results?
    A: Hold the probe at a shallow angle and apply light, even pressure along the weld, marking suspect areas for repair rather than forcing the probe.
