TQC releases Low Voltage Pinhole Detector

The TQC Low Voltage Pinhole Detector is available in two models. The basic model has 9V and 90V mode. The Advanced model also has 24V and 67,5V modes. Both models are microprocessor controlled and equipped with a color display, automated self-diagnostics, ground failure indication, pinhole counter, acoustic-, visual, and vibration indicator.

Application

Coating irregularities can be due to a number of different causes. Surface contamination or unsuitable climate conditions prior to the application, holidays or entrapped dust or air bubbles may lead to issues like pinholes. .

Outdoor or underground coating applications which are likely to have various degrees of fluid exposure can be susceptible including areas like inner linings of tanks and pipes. Pinholes in those systems will inevitably lead to a premature coating failure so detection at an early stage is critical. .

The correct Voltage depends on the coating thickness; 9 volt for coatings up to 300 micron; 67.5 volt for coatings up to 400 micron; 90 volt for coatings up to 500 micron.

The TQC Low Voltage Pinhole Detector consists of a battery operated instrument with ground lead and a wet sponge electrode. The ground lead is connected to the bare substrate. Movement of the wetted sponge over the test area allows moisture to pass into the pinhole due to capillary absorption thus making contact with the base substrate which acts as a ground. causing either an audible, visual or tactile / vibration alarm to indicate a pinhole. The number of detected pinholes is stored in memory, and remains available after power down , even when replacing the batteries.

Operating the TQC Low Voltage Pinhole Detector is very easy, The interface is menu based and intuitively operated by a single button.
