Overview
LEEB Leeb710 spark detector is a metal anticorrosive coating mass detection instrument with intuitive and convenient pointer display. It adopts an integrated high voltage generator to overcome static electricity, with stable and reliable performance and perfect sound and light alarm functions. It is especially suitable for field operations and is widely used in chemical, petroleum and other industries.
Features
1. The pointer display is intuitive and convenient
2. Adopt integrated high voltage generator to overcome static electricity
3. Stable and reliable performance, widely used in the industry
4. Sound and light alarm function is perfect
5. Especially suitable for field operations
6. Nickel-metal hydride battery power supply, with high capacity, long life, light weight, no pollution, no Memory effecy, fast charging and discharging and other advantages
Principle
The spark detector applies a certain amount of pulsed high voltage to the surface of the conductive substrate anti-corrosion layer, when the anti-corrosion layer is too thin, metal leakage or air leakage pinholing, the pulsed high voltage passes through to form an air gap breakdown and generate spark discharge, while sending a pulse signal to the alarm circuit, so that the alarm emits an audible alarm, so as to achieve the purpose of detecting the anti-corrosion layer.
Applications
Chemical, petroleum, rubber, enamel and other industries
Steps
1. Apply a pulsed high voltage to the surface of the conductive substrate anti-corrosion layer
2. Observe whether there is a spark discharge phenomenon
3. Listen to whether the alarm sounds
4. Determine the mass of the anticorrosive layer according to the spark and alarm situation
