Mitech SKU: MTH-7D Barcode:
The Mitech MTH-7D Digital DC Spark Leak Detector is a professional-grade inspection tool designed for fast and accurate detection of defects in anti-corrosion coatings. Whether you're working on pipelines, tanks, cables, or ship hulls, this portable device identifies pinholes, cracks, and weak spots by generating a visible spark and audible alarm at the flaw location.
Engineered for on-site operations, the MTH-7D is powered by a 12V high-capacity battery pack, eliminating dependence on fixed power sources. Its intuitive controls, adjustable high-voltage output, and real-time LCD feedback make it a go-to solution for industrial maintenance and coating inspection.
Wide Detection Range: Suitable for coating thicknesses from 0.05 to 10 mm.
Adjustable Output Voltage: Ranges from 0.2 kV to 30 kV (±5%), adaptable to different coatings.
Battery-Powered Mobility: Operates on 12V DC, perfect for remote and field applications.
LCD Display: View real-time voltage output for precise monitoring.
Flexible Probes: Comes with two standard probes; customizable for specific needs.
User-Friendly Design: Lightweight, compact, and simple to operate with low power consumption.

By applying a high-voltage pulse to the anti-corrosive coating, the MTH-7D detects flaws where the voltage breaks through, causing a spark and triggering audio/visual alarms. This allows for precise pinpointing of coating integrity issues.
Operate in dry, clean environments.
Avoid exposure to moisture or corrosive gases.
Ensure proper grounding during use.
Do not use while charging.
Keep probe and tested surface dry and clean.
Avoid probe contact with grounded surfaces.
Select proper probe type and maintain optimal spacing during inspection.
