High Voltage Pinhole Detector Portable Holiday Detector Nondestructive Flaw Detection
OVERVIEW
HD-101 Holiday Detectors are employed in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for anti-corrosion protection over metal and concrete (conductive) surfaces.
With corrosion an extremely costly and disruptive worldwide problem, preventative determination becomes essential.
For newly constructed tanks, pipelines and other installations, where corrosion prevention coatings have had to be applies, specifications will normally. Meanwhile, as well as apply in porcelain enamel industry.
Call for a specific coating to a specific thickness. By using our Detector to verify the competency of the sealing coatings, the contractor can be assures that his coatings responsibility has been met. In terms of cost effectiveness, with the low capital and operating costs of the Detector, the contractor will have some protection from claims at a very low price.

HOW TO CHARGING
1 Before Charging, must switch the main unit off. Plug the charger into 220V electrical outlet,
and connect another bottom with the item m charge connector. Then, the item g Charging indicator is bright.
2 Passing 8 to 10 hours, Charging completed and the item G Charging indicators turn out...
3 Note
When the battery is power enough,
the item f Low Power indicator is not light. When the battery power remain 10V or less,
The item f will be light and must be recharged to the battery if it commits a particular offence or number of vehicles.
