DJ-9 is a pulse high-voltage instrument, is used to detect the quality of metal coating anti-corrosion coating of special equipment, and other direct current spark leak detector compared to the reduction of the anti-corrosion layer The use of this instrument can be of different thickness of glass-lined, glass steel, epoxy coal tar pitch and rubber lining and other coatings, for quality testing.Therefore, the use of this instrument can improve the efficiency of the operator's work. When the coating has quality problems, such as pinholes, bubbles, cracks and cracks, the instrument will issue a bright spark, while sound and light alarm. As is the battery-powered, it is particularly suitable for field operations. The instrument design is advanced, stable and reliable, can be widely used in chemical, petroleum, rubber, enamel industry, is used to detect the quality of metal corrosion coating an essential tool.

2, the output voltage: 0.5kv ~ 30kv (stepless adjustable)

3, leakage point memory: the largest 99 points

4, the output direct indication of high pressure

5, DC power supply: 12V

6, the power consumption: about 6W

7, the host volume: 220 × 130 × 88mm3

8, blue background light

9, instant boot, automatic power off

10,3-bit LCD display output voltage, 2-digit LED display anti-corrosion layer leak, full touch panel

11, the alarm: headset, buzzer double alarm

EDM Leak Detector DJ-9 detection principle and structure of the brief:

Detection principle: electric spark leak detector is through a variety of conductive substrate coating surface with a certain amount of pulse high voltage, such as because the coating is too thin, leakage of metal or air leakage pinhole, when the pulse pressure after the formation of gas Gap spark and spark discharge, at the same time to the alarm circuit sent a pulse signal, so that the alarm sound alarm, so as to achieve the purpose of testing the coating.
