The INSIZE 9511-HA30 Holiday Detector is a professional-grade non-destructive testing (NDT) instrument designed for inspecting the integrity of anti-corrosion coatings. It utilizes adjustable pulse high-voltage to detect cracks, pinholes, or thin areas in various insulating coatings, including glass lining, rubber lining, insulating paint, coal tar epoxy, and glass fiber reinforced plastic.
- Detection Mechanism: Employs pulse high-voltage to identify coating defects. When the probe moves over a crack or pinhole, gap gas breakdown occurs, triggering a discharge spark.
- Alert System: Integrated sound and light alarm on the probe, with support for headphone audio monitoring.
- Display: Equipped with an LCD screen featuring a light-control backlight for visibility in various lighting conditions.
- Portability: Designed for field use with a built-in rechargeable Ni-MH battery.
- Power Management: Features an automatic power-off function to conserve battery life.
- Customization: Measuring range can be customized for coatings exceeding 10mm in thickness; arc brush and circular probe options are available upon request.
