User manual for Elcometer 270/280/266 microvoid and porosity detectors, covering wet sponge, high voltage, and UV detection methods.
This manual describes the Elcometer 270/280/266 microvoid and porosity detectors, designed for inspecting coatings on conductive substrates. The 270 model uses a wet sponge technique for coatings under 500μm, while the 280 uses pulsed DC high voltage for thicker coatings up to 25mm. Both models include safety features, adjustable voltage, and various interchangeable probes. Accessories like extension cables and replacement sponges are detailed for different inspection scenarios.
The manual also covers detection methods including wet sponge, high voltage, and UV fluorescence, with technical specifications, calibration, and compliance with international standards such as ASTM, ISO, and NACE. This manual is written in Chinese.
