Low Voltage Pinhole Detector

Description

What is Low Voltage Pinhole Detector?

Low voltage pinhole detector, also known as the wet sponge technique, is use to test relatively thinly coating substrates. Positest LPD are effective for coating thicknesses of 500 microns or less. This detection method is suitable for identifying pinhole defects only.

We provide two type of low voltage pinhole detector as follow:

TQC Low Voltage pinhole detector.

TQC Low Voltage Porosity Pinhole detector , enables the user to inspect various coatings on conductive substrates for small defects, such as holidays and pinholes using the ‘wet sponge technique according ISO 8289-1’. This document specifies two low voltage tests for detecting and locating defects that extend to the basis metal in vitreous and porcelain enamel coatings. Method A (electrical) is applicable to the rapid detection and determination of the general location of defects. Method B (optical), based on colour effects, is applicable to the more precise detection of defects and their exact locations. Both methods are commonly applied to flat surfaces. For more intricate shapes, such as undulated and/or corrugated surfaces, ISO 8289-2 is applicable.

The grounding clamp is connected to an untreated piece of the substrate (which is electrically connected with the measurement area), where the wet sponge will be used to probe the entirety of the coating with the selected voltage applied. When current flows from the sponge wand to the grounding clamp then that indicates a defect in the coating. The user will be notified using the selected feedback method(s). (Buzzer, vibration, headphones and also display.

Pinhole Detector is available in both two models: Basic 9V / 90V and Advanced 9V, 24V, 67,5V and 90V.

The number of detected pinholes is stored in memory. It will remains available after power down, even when replacing batteries. But an user also can clear the memory.

FEATURES

• Color Display with battery indicator and also menu based user interface
• Intuitive single button controls
• Visual, audible and also tactile feedback*
• Return cable connectivity detection*

• Depending on model

To have full access in any area a special Low Voltage Expansion Kit is available. This kit comes without the Low Voltage Pinhole Detector, and also the standard accessories that can stored in the carry box. The kit comes in a sturdy suitcase that contains a telescopic stick, roller-sponge, spare sponge, universal clamp, customize able sponge, pair of scissors, magnet ground clamp, plastic bottle, 10 m cable 4 mm, 1,25 m cable 4 mm, and also M6 hexagonal adapter.
