Device description
Corona pulsed holiday detectors are precise, easy-to-use portable devices for detecting porosity, pinholes, leaks, cracks, tears and other defects in protective dielectric coatings, linings and membranes.
ASTM D4787/D5162/D6747/D7953/G62, ISO 29601, NACE SP0188/SP0274/SP0490, AS3894.1
- The test voltage disappears when the key on the handle is unpressed eliminating accidental contact with the electrode.
- The device has a ground wire contact detection feature. Without a ground wire, the test voltage will not turn on!
- The device's primary function is to accurately determine the coordinates of a coating defect. Corona ensure precise detection of coating defects by a built-in test voltage stabilizer and an algorithm for filtering external electrical noise.
- The device has a user calibration mode and settings for a specific tested object.
- The device comes with a calibration certificate.
- To start testing, you only need to press one key.
- The device calculates the test voltage and sensitivity level automatically.
- The lightweight, ergonomic design allows you to wear the device on your shoulder or belt.
- The kit includes everything for quick start.
