A voltage from the battery supply is transmitted through the probe and dampened sponge attached. Because the instrument's earth is connected to the substrate, when a flaw is encountered, the conductive path is made and the alarm sounds.The unit features three test voltage options; 9V for coatings up to 300um, 67.5V for coating assessment to ASTM standards, and 90V for coatings up to 500um.Please note: while the PCWI Wet Sponge Detector has a maximum range of 500um, we highly recommend that coatings over 150um, or coatings in corrosive environments, be high voltage porosity tested Kit Contents PCWI Compact Wet Sponge Pinhole TesterHandle including SpongeBelt/Pocket clipSeven metre earth lead and clipConformance CertificateOperating InstructionsCarrying Case Click image for more info Features LED display of voltageInternally mounted 9 Volt batteryLow battery condition LED indicatorAudible and visual fault alarmsTelescopic handle for user confort (extends to 4/1.2 m)Large probe head (9" x 1.57"/230 x 40mm) and wider sponge gives faster tests.
