KODIN-6DJ is a smart pulsed high-voltage anti-corrosion coating quality detection instrument, which adopts high anti-interference intelligent chip, high anti-interference liquid crystal screen and brand-new digital control circuit, so that the instrument's high voltage output is more accurate, can be controlled in the range of ± (0.1KV + 3% reading), according to the thickness of the anti-corrosion coating automatic output of the appropriate measurement voltage. This instrument integrates the professional industrial design concept of Kedian, so that the instrument operation is more humanized. Because it is powered by a large capacity lithium battery, it is small and light, so it is particularly suitable for outdoor work.
