Holiday detectors(porosity detector,pinhole tester,spark tester,jeep tester or jeeper)
The intelligent
frequency conversion holiday detector uses intelligent frequency
conversion high voltage detection technology, used to detect pinholes,
cracks and other damage and defects in non-conductive coating on
conductive substrate (such as metal), can be used to detect the quality
of insulating and anticorrosive coating on the surface of storage
tanks, valves and pipelines. Host for portable, rugged ABS shell, the
instrument appearance design is advanced, stable and reliable
performance, can be widely used in anticorrosive engineering, plastic
airtight joint detection, concrete coating layer air tightness test,
petrochemical pipeline corrosion inspection, enamel production
industries, is used to detect an essential tool for metal surface
insulating anticorrosive coating quality.

Detection
principle:
Spark
detector is based on a variety of conductive insulating coating on
substrate surface to add a certain amount of pulse pressure, such as
anti-corrosion layer, thin metal or pinhole of leak leakage, when pulse
high voltage, air gap will be punctured and produce spark discharge, at
the same time send pulse signal to alarm circuit, the alarm sound and
light alarm, so as to achieve the aim of the anticorrosive layer of
quality testing.
Notice
for operation:
1.
Before use, the operator should read the instrument instruction
carefully, strictly follow the operation specifications, pay attention
to the protection of the instrument, prevent fall, collision and high
temperature, do not place near the humidity and corrosive gas.
2.
Select a proper ground point to ensure test quality.
(1)
small volume of metal surface anti-corrosion layer detection, to be
detected by the object with insulation support more than 20cm, and then
the grounding wire is well connected to the metal object detection.
(2)
For the detection of large volume or flat objects, when the measured
object has good contact with the earth, only the grounding wire access
to the earth can be tested.
3.
During testing, testing personnel should wear high-voltage insulating
gloves, and no one should touch the probe and the object under test, in
case of electric shock!!
4.
The surface of the tested anticorrosion layer should be kept dry. If
there is conductive layer (dust) or water, it is not easy to determine
the exact location of the leak point.
5.
Power switch must be turned off when the instrument is not in use!!
6.
When the undervoltage indicator lights up, please be sure to charge in
time!!
Stable
output voltage of high voltage gun!!

HD-006 Holiday Detector:
Holiday Detectors are employed in the
non-destructive detection and location of pinholes, bare spots or thin
points in protective coatings applies for 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 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.
Complies with Standards: ISO 2746, BS
1344-11, ASTM G 6, ASTM G 62, ASTM D4787, ASTM D5162, NACE RP 04901,

Wet sponge holiday detector:
SHD001 Wet
Sponge Holiday Detector has received wide acceptance in
the corrosion control and industrial painting industry as a device for
locating bare spots (or holidays,cracks etc) in the thin protective
films which are sprayed or brushed on metal or concrete surfaces. This
pinhole detector is non-destructive with low voltage of 9V,67.5V,90V DC
output.
The inspection electrode consists of a 168×68×28mm
cellulose sponge which, when dampened with water, is moved over the
coated surface. When the electrode passes a void or bare spot, a small
current flows and actuates an audible signal in the instrument. The
damp sponge provides an electrically conductive film that contacts the
surface being inspected and insures good inspection even in corners and
around irregular shapes where holidays are most likely to occur.
Features
- Non-destructive, sponge-type holiday
detector.
- Regulated 9V,67.5V,90V DC output.
- With LED light indicator for each voltage
- Li-pol batteries readily available
anywhere.
