Caltech India is manufacturer and exporter of latest designed latest technology holiday detectors. We manufacture and export all types of holiday detectors for pipeline at economical price. To buy holiday detector drop us an enquiry.
Function of holiday detector is to test and detect pinholes, porosity or flaws in insulated coatings on conductive substrates.
The holiday detector is also known as a holiday tester, porosity detector, pinhole tester, spark tester, jeep tester or jeep meter. A Holiday detector is a non-destructive detection method of testing.
Holiday test machine model HD 05 DC holiday detector has range of 0-5KV DC. Holiday Detector is portable fully digital holiday detector is used for quality control inspection instrument. It is used to electrically locate and fault find in defects of protective coatings. Audible and visual alarms are activated when a flaw is detected using holiday detector rubber brush and electrodes. This makes holiday detection procedure very easy and operator friendly.
Holiday test for pipe / holiday detector is suitable for all types of coatings like fusion bonded epoxy, coal tar epoxy, paints, polyester, polyurethane, pipeline tapes, heat shrinks and asphalt. Holiday tester is versatile unit can be used to inspect protective coatings applied to pipelines, tanks, pilings, fire lines or buried pipelines of conductive surface. Holiday test method is very simple. A test voltage is applied to the coating by moving a brush probe across the surface and where there is either a pinhole or flaw the voltage will spark through the coating at the flawed location a red flashing indicator will flash and an audible alarm will sound the detected flaw can now be marked for subsequent repair and testing resumed for the remaining surface area, if no flaws are detected the test will therefore be non-destructive test method.
The value of the test voltage is achieved by the dielectric or voltage strength of the coating thickness. Therefore 1000 micron would by approx 3kv to 5kv test voltage. The Instrument can be used as per AS 3894.1, ASTM D4787, ASTM G6, ASTM D5162, BS 1344-11, ISO 2746, NACE RP0274, NACE RP0490, NACE RP0188-88 standards. In every holiday test equipment, accurate voltage setting is achieved by adjusting a knob to desire voltage is displayed on a digital display with increment of 0.1KV. Internal jeep tester ensures that the selected voltage equals the test voltage.
Buy Holiday Detector that are supplied with calibration certificates with traceability as per international standards.
Holiday test instrument gas automatic fault detection feature installed which ensures that are detected at any voltage setting. The Instrument has low voltage battery indication for safeguard the batteries and ensures desired voltage all the time.
Porosity Detector is lightweight and overall weight with handle is approx 3.6 kg the test voltage is of low power and does not damage or cause burn marks on the coating. When the using holiday detector there are a number of important safety features built in the test voltage is high impedance and drops to zero when a fault is detected, earth cable is lockable to prevent accidental disconnection. In view of the many different holiday testing applications there is an extensive range of accessories available including circular brushes for pipe work internal, rolling springs for pipe work externals, broad brushes to allow for quicker measurement of large surface areas and insulated extension rods.
Holiday tester is supplied in a carrying case complete with conductive rubber brush, neck strap, earth cable, batteries fitted along with operating manual giving holiday detection procedure and calibration certificate Other special size circular internal rubber brushes, external brass electrodes and external rolling spring electrodes can be manufactured to order at highly economical price
To verify holiday detector test equipment output voltages, we also supply high voltage measuring device generally called as jeep meter or PRM Meter. Caltech engineering Services – India offers full range of holiday detectors for engineering construction and maintenance of paints and coatings. Buy Holiday Detectors with high quality, better technology and at an economic price. We also manufacture and export wet sponge holiday test equipment also known as wet sponge pinhole detector PD-990.
