Doing our own PMI tests in house has come up as a possibility, since the recent accident in China I think it was, and I am trying to find prices on the units used to carry out the test.

   Does anyone have ant routes to purchasing something like this, or on an XRF analyzer.
  
   The purpose would be to check the incomming pipe and other materials that we recieve for authenticity.

   i appreciate any help y'all can offer! THANX
