AT-5H DC spark leak detector Is a specialized instrument used to detect metal anti-corrosion coating quality, the use of the instrument can be of different thickness

Glass, fiberglass, epoxy coal bitumen and rubber lining coating quality inspection. When the coating quality questions,

If there was a pinhole, bubble and crack, bright spark instrument and sound alarm. Because it is a nickel-hydrogen battery

(The battery with high capacity, light weight, no pollution, no memory effect, can quickly charge and discharge, and other advantages, is an ideal green ring

Product. ), They are particularly suitable for field work. The apparatus of advanced design, stable and reliable, can be widely used in chemical industry, petroleum, rubber

Plastic, enamel and other industries, is an essential tool used to detect metal anti-corrosion coating quality.

Detection principle:

Spark detection equipment is based on conductive substrate surface coating plus a certain amount of high voltage pulse, such as coating the book, missing gold

Or leakage pinhole when the pulse high-voltage passing, formed the breakdown and spark-gap discharge, as well as alarm circuit sent a

Pulse signal alarm audible alarm, so as to reach the goal of coating detection. The second, main technical parameter:

1 for detecting thickness: 0.2mm~ 20mm

2, output voltage: 0~ 6KV, 5K~ 30KV (10%) (Stepless adjustable)

3, the output high voltage direct instructions

4, DC power supply: 12V

5, power consumption: 6W

6, master volume: 170x160x70mm

7, weight: 1.6kg
