Product Description
HUATEC HD-105 High Voltage Pinhole Detector
Product Overview
The HUATEC HD-105 is an intelligent pulsed high voltage coating quality detector designed for precision testing of protective coatings. Featuring anti-interference technology, digital control circuits, and adjustable voltage output, this portable detector ensures accurate identification of coating defects including pinholes, porosity, and thin spots.
Operating Principle
When the high voltage probe passes over non-conductive coatings, any thin spots, leaks, or pinholes cause air gap breakdown and spark discharge. The detector automatically records these leakage points while providing audible and visual alerts.
Applications
Widely used in chemical plants, oil facilities, rubber manufacturing, and enamel coating applications. Essential for quality control of metal anti-corrosion coatings across industrial sectors.
Key Features
- Intelligent anti-interference chip and LED display
- Precision voltage output: ±(0.1KV + 3% reading)
