PRODIG-TECH Paint Thickness Gauge GL-3S-UV with Integrated UV Lamp and LED Flashlight

In a busy body shop, a technician runs the GL-3S-UV over a freshly painted fender, checking the clear coat depth before final polishing. This PRODIG-TECH gauge instantly identifies ferrous and non-ferrous substrates, delivering precise readings from 0 to 2000 µm on steel, galvanized steel, and aluminum. The integrated UV lamp reveals hidden imperfections while the LED flashlight illuminates dim wheel wells, making it a must-have for automotive paint inspection and industrial coating work.

Why choose it

The GL-3S-UV combines precision, versatility, and convenience. Its dual UV and LED lighting sets it apart from standard gauges, allowing you to detect paint defects and work in dark areas without extra tools. Automatic substrate recognition eliminates guesswork, while the high-resolution sensor ensures reliable readings on both ferrous and non-ferrous metals. The backlit display and one-handed operation make it easy to use in any position, and the generous memory lets you review measurements on the spot.

Ideal use cases

• Automotive paint inspection: verify clear coat and total paint thickness on body panels
• Industrial coating measurement: check powder coating, anodizing, or plating on metal parts
• Quality control in manufacturing: ensure compliance with coating specifications
• Used car evaluation: detect repainted areas or body filler
• Marine and aviation maintenance: inspect protective coatings on aluminum and steel

Good to know

The gauge comes ready to use with calibration plates, reference foil, batteries, and a protective pouch. It supports µm, mm, and mils units, and the automatic power-off function saves battery life. The operating temperature range is -20°C to +40°C, making it suitable for most workshop environments.
