I came up with a virtual 1 to 1 corrospondence between PPM [ as determined by AA spec] and microsiemenes 'including' a 15% particulate count [85% ionic] in two different samples. The conductivty readings were the same between measurement devices within tenths of a microsiemen [PWT was calibrated correctly]
Adding 15-20% might not always be 'the way'. Ode At 09:50 AM 4/7/2004 -0700, you wrote: >Hi Mike, > >The PWT reads from 0-99 with stated accuracy but can actually go to 199 >before going off scale.
