EOS crackle test tubes can be used to perform a crackle test.
What does it do?
Although no longer part of BS EN 60422:2006 the crackle test is still widely used as a quick and simple indication of the presence of free water in a sample of insulating oil due to incorrect storage or poor sampling technique.
Things to remember
The EOS Crackle test tubes are supplied in boxes of 100 and measure 16 x 150mm each.
