Special equipment KD-3 spark leak detection of metal anti-corrosion coating for quality

KD-3 spark leak | special equipment used to detect metal corrosion coating quality an overview KD-3 type spark leak detection thickness: 0.5 ~ 10mm, output voltage: 0.2kv ~ 30kv, is the use? to detect metal corrosion coating quality of special equipment, the use of this instrument for different thicknesses of glass-lined, glass, steel, coal tar epoxy coatings and rubber linings for quality testing. When the coating quality problems, such as pinholes, bubbles, fissures and cracks, the instrument will emit a bright spark, while an audible alarm. Because it is powered by batteries, it is especially suitable for field work. The instrument design advanced, reliable, and can be widely used in chemical, petroleum, rubber, ceramic industry, is an essential tool used to detect metal corrosion coating quality. Second, the characteristics? Using digital circuit control and pulse generation principle. Unique one-touch switch, automatic charging into the charging state, digitizing circuit structure makes indication more stable, more stable high-voltage pulse is detected. Aluminum chassis make the machine more attractive, strong and durable. Third, the product performance suitable for detecting thickness: 0.5 ~ 12mm output of high pressure: 0.2kv ~ 30kv ????? (stepless adjustable) output high voltage DC power supply value is a direct indication: 12V Power consumption: about 6W host volume: 210 × 120 × 88mm3 white background light-touch switch 3 LCD output voltage, wide touch panel warning:? headphones, buzzer Dual alarm four, detection principle and structure outlined Detection principle: spark leak through a variety of coating the surface of the conductive substrate plus a certain amount of pulse pressure, as a result of the coating is too thin, a pinhole leak leakage metal or when the pulse high voltage passed by, and the formation of a spark discharge gap breakdown, at the same time to send the alarm circuit to a pulse signal to the alarm sound the alarm, so as to achieve the purpose of coating detector. ?
