Hi Technet members I have a stencil and mis-print cleaner on-site which has a water purification circuit attached. It consists of a Carbon and a D.I. cylinder and I need to plumb in a meter for measuring the purified water. I have only ever used resistivity systems previously, but have now discovered conductivity meters. The only thing I have been told about them is that they can measure to a tighter degree than resistivity meters. If anybody can enlighten me unto which system would suit my application best, then it would be greatly appreciated. Thanks in advance Dave Abbott Manufacturing Engineer Marconi Communications --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
