Pinhole Detectors or wet sponge tester detects pinholes, voids, thin spots, foreign inclusions, or contamination in coatings film. Dielectric srenth of film also refered as holiday detection.

A low voltage holiday detector / wet sponge tester operation is by the application of a wet sponge to the coating. The wetting agent penetrates any pinhole and makes a conductive path through to the substrate, the pin hole detector automatically detects this conductive path and sounds an audible alarm and also gives a visual warning by a flashing red indicator that a pinhole fault has been detected. The flaw can now be marked for repair and further testing resumed. Coating on metals prevents to corrode unless a protective coating is applied. Pinholes based on wet sponge method generally caused by air entrapment that is then released from the surface, or by the entrapment of particulates (dust, sand, etc.), which do not stay in place. High voltage holiday detector is used for testing coatings above 500µm and low voltage holiday detector (Pinhole Detector ) is used below 500µm of coating on metallc substrates.

Caltech Engineering Services- India offers basic and standard DCVG equipment.
DCVG-UK manufactured useful equipment. when DC is applied to a pipeline in the same manner as in cathodic protection, a voltage gradient is established in the ground due to the passage of current through the resistive soil to the bare steel exposed at a coating fault.

The voltage gradient becomes larger and more concentrated the greater the current flowing and the closer you are to a coating fault location. In general,  the larger the fault, the greater the current flow and hence bigger the voltage gradient.

The direct current voltage gradient method (DCVG) uses a sensitive mili-volt meter, to indicate the potential difference between two copper/copper sulphate half cells placed in the soil in the voltage gradient at ground level. If spaced two metres apart in a voltage gradient, one half cell will adopt a more positive potential than the other, which thus enables the size of the gradient and direction of the current flow causing the voltage gradient to be established.

The Model PD Detector and null Method have been well accepted by the industry. Acclaimed to be the fastest method known to accurately locate points of electrical contact and insulating joints on coated pipelines. This type survey may be conducted on coated pipelines regardless of their location. Unaffected by parallel lines, depths or cover, the survey can often be, in part, conducted from a moving vehicle over the pipe. In brief, the Null Method follows the flow of impressed audio frequency current in a coated pipe and determines where it leaves. The point of current discharge is determined by a sharp disturbance of the null itself rather than the signal level of the audio frequency. This method is quite practical, particularly as competent field personnel can interpret findings quickly and accurately.

The oscillator provided with the set has been designed to use the latest developments in this type of instrumentation. A signal of 750 c.p.s. is generated by using a power transistor switching circuit. This arrangement eliminates troublesome vibrators, buzzers or other moving part elements.
