Frequently Asked Questions

Q: What materials is the SWT-NS004 Spark Tester compatible with?

The SWT-NS004 is designed for geomembranes and synthetic liners used in environmental protection, specifically those with thicknesses between 3mm and 30mm.

Q: How does the spark testing process identify a leak?

It uses high-voltage radio waves. When the tester passes over a defect like a pinhole or crack, the current jumps (sparks) through the hole, signaling a leak.

Q: Can this device detect bubbles in the weld?

Yes, the device is specifically engineered to identify bubbles and other internal fusion defects that could compromise the waterproof seal.

Q: Is the SWT-NS004 easy to operate for field technicians?

Absolutely. It is designed for durability and ease of use in the field, featuring a straightforward voltage adjustment system for various site conditions.

Q: Why is spark testing better than visual inspection for geomembranes?

Visual inspection cannot detect microscopic pinholes or internal voids. Spark testing provides scientific, electrical verification of the weld's integrity.

Q: What voltage range is recommended for different thicknesses?

The device offers a wide range from 10kV to 55kV. Generally, thicker membranes require higher voltage to effectively bridge the gap and detect leaks.
