Following Graham Collins reply, I might only add that if you are trying to compare the 2 systems, then you should be aware of the Equivalency Factor that is/was used by the US Military for each piece of equipment. I may be able to get you a copy of this info if you wish. Additionally be aware that there are 2 types of Ionic (ROSE) testers. Dynamic and Static types. Essentially (lest SIRDoug or other eminences nail me to the TechNet Totem Pole) The Dynamic tester cleans up the entire solution in the bath and then measures the same total solution volume for resistivity changes. The Static tester uses a pre-defined volume of solution which alone is recirculated for resistivity changes / ionic measurements. I am not sure whether the Zero-ION is Static or Dynamic. Certainly Trek Industries make the ICOM5000 which is a Static Tester most others are Dynamic. Hope this helps Regards, Graham Naisbitt [log in to unmask] WEB: http://www.concoat.co.uk CONCOAT Ltd Alasan House, Albany Park CAMBERLEY GU15 2PL UK Tel: +44 (0) 1276 691100 Fax: +44 (0) 1276 691227 ----- Original Message ----- From: F.Shigeoka(Ueno-Seiki) <[log in to unmask]> To: <[log in to unmask]> Sent: 17 January 2000 07:36 Subject: [TN] Omega meter v.s.
