Portable Holiday Detector For Industrial Coating Leak NDT Testing

Industrial NDT Holiday Detector for coating leak inspection

HD-12 holiday detector is a new intelligent pulse high voltage instrument,adopt high anti-interference intelligent chip,High anti-interference LCD screen and brand-new digital control circuit,Make the instrument high voltage output more accurate + (0.1KV+3% readings),the operation is more intelligent and humane.

HD-12 electric spark leak detector is a special instrument for detecting the quality of metal anticorrosive coating.This instrument can be used for different thickness of glass, glass fiber reinforced plastics, epoxy coal tar and rubber lining coating,carry out quality inspection.When the quality of the anticorrosive coating is in doubt,such as pinholes, bubbles, cracks and cracks,the instrument will give off a bright electric spark,sound and light alarm at the same time.Because it is powered by NiMH batteries,small in size and light in weight,therefore, it is especially suitable for field operation.The instrument is advanced in design, stable and reliable,it can be widely used in chemical, petroleum, rubber and enamel industries,it is a necessary tool for checking the quality of metal corrosion resistant coatings.

Main features:

1. 0.5KV～30KV Full range high voltage generator;
2. Accurate and steady measuring voltage is acquired by software intelligent control,ensure that the display voltage is the test voltage,voltage accuracy:±(0.1KV+3% reading);
3. Suitable measuring voltages can be automatically output based on the material and thickness of the coating;
4. High pressure safety switch : High voltage start with bright LED alarm prompt and icon display on screen,protects users from spark damage;
5. When pore is detected,in addition to edm,the instrument will also send out audible and visual alarm signals,and accurately record the needle hole number(maximum 999);
6. You can set the limit of the number of pinholes,exceed the pinhole limit value, the instrument alarm automatically;
7. 128*64 LCD display,display measuring voltage,pinhole number,battery indicator,menu and other instruments, data, information;
8. New modern sense of design,industrial dustproof waterproof sealing casing;
9. Large capacity 4000mA lithium battery ensures long working hours;
10. Humanized full touch panel, automatic backlight button;
11. Pulsed discharge,small discharge current,stop twice damage to anticorrosive coating,save power and prolong working hours,it can also be alleviated because of improper operation causes electrical shock to the human body.
