Porosity - Holiday testing is much easier than it used to be thanks to PCWI

 

Testing coatings was much more difficult before PCWI made everything you need readily available.

When we did this job in 1978 we had to manufacture our own brushware and use the bulky Pulse DC porosity detectors which didn't produce a stable voltage output. We changed over to the DC detectors when they became available, they were a little more stable, although they were not able to maintain constant test current over the voltage range.

The modern units are easy to use, light weight, with a stable constant voltage and test current for much better test results.

Porosity testing was much harder in the old days with cumbersome equipment
