The TQC low voltage 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,’ notes a write-up from Amkette Analytics Ltd, their agents in India.
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, this indicates a defect in the coating. The user will be notified using the selected feedback methods like buzzer, vibration, headphones and/or display.
The TQC Pinhole Detector is available in two models: Basic and Advanced.
The number of detected pinholes is stored in memory, and remains available after power down, even when replacing batteries. This memory can be cleared by the user.
The unit features a color display with battery indicator and menu based user interface; intuitive single button controls; visual, audible and tactile feedback; return cable connectivity; smart power saving features and automated self diagnostics depending on the 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; however the detector and its standard accessories can be stored in it. The kit comes in a sturdy suitcase that contains a telescopic stick, roller-sponge, spare sponge, universal clamp, customizable sponge, pair of scissors, magnet ground clamp, plastic bottle, 10m cable 4mm, 1.25mm cable 4mm, and M6 hexagonal adapter.
