The SENNR series intelligent variable frequency EDM pinhole Detector uses intelligent variable frequency high Voltage detection technology to detect pinholes, cracks and other damage and defects in non-conductive coatings on conductive substrates (such as metals), and can be used to inspect the quality of surface insulation and anti-corrosion coatings such as storage tanks, valves and pipelines. The host is a portable, sturdy and durable ABS shell, the instrument has a professional appearance design, stable and reliable performance, and can be widely used in anti-corrosion engineering, plastic closed joint detection, concrete coating air tightness testing, petrochemical pipeline anti-corrosion testing, enamel production testing and other industries, and is a required tool for testing the quality of metal surface insulation and anti-corrosion coatings.

A special metal hose protects the connection cable between the main machine and the high-Voltage generator;
Military-grade gold-plated connectors to ensure the reliability of the connection;
Unique appearance design, ABS chassis, beautiful and durable;
Light-touch waterproof membrane keypad, simple and convenient operation; AC and DC power supply can be quickly and automatically switched, AC and DC dual-purpose;
Large-capacity lithium-ion battery pack, energy saving and environmental protection;
Independent high-Voltage button to better protect the safety of inspectors and comply with international safety standards;
The intelligent variable frequency high-Voltage detection technology is suitable for use in humid environments, and does not generate static electricity during the detection process;
It can detect dew-wetted or sludge-stained surfaces and slightly conductive surfaces;
It can automatically identify different working probes (high-pressure guns) and calibrate them by themselves;
Digital display of battery Voltage and output high Voltage;
When pinholes and other defects are detected, sound and light alarms, and the number of pinholes and defects can be counted;
The output high Voltage can be accurately adjusted, and the display accuracy is high.
With overload protection function;
