Is anyone monitoring PH from the aqueous washer waste stream when using
Deionized water and Organic flux? If so, what type of meter are you using due
to the problem of measuring PH in high purity water. We are currently testing
the use of a resistivity meter and correlating the resistivity to PH. The
readings are not consistant which creates a problem for Industrial waste water
regulators. If anyone has any solutions, you can email me directly at
[log in to unmask] or telephone (619) 452-4734.
