I have never stated that the highest PPM we can achieve is 20 PPM and I have never indicated there is 20% oxide fudge factor. I do say that we calibrate our CS generators to put out at least 20 PPM ionic content and the fudge factor is to add 20% for the colloidal portion which is not read by the PWT meter. We have calibrated the SG7 to produce 30+ PPM (ionic) for some customers but normally set them for 20+ PPM. > But now you now state you can make 45 ppm that is crystal clear.

You want to do a salt test. You are so scientific in everything you talk about but you think a test so subjective as using salt is the way to test CS. I think reading a digital readout is a much better way to go. At least my eye can't sway the reading. It is what it is. Of course I won't send you any. It would be a waste of my time and money. > Trem, here are my credentials: 31 years experience designing > precision instrumentation in high-volume disk manufacturing. > Invented a technique to measure the bit error rate of disk drives > that became a worldwide standard and saved the industry hundreds of > millions of dollars. > > I have 6 patents issued.

It's your attitude that gets to me. I never questioned your ability to quote formulas and technical jargon so why are you defending yourself? > A relay also has measurable leakage and cannot be used in some > sensitive circuits I design. But the greatest problem with leakage > currents is the pcb itself. Look up "guard ring". I know what a guard ring is. It has no purpose in the type circuitry we use. Look, you and I know this is not that sophisticated design work and what a business tries to do is produce an item that will work well, not fail in service, be easy to operate and make a reasonable profit. Of course one can go to the Nth degree in designing something but it will most likely fail in the marketplace because it would be too expensive to compete with other comparable units. > The residual flux used in soldering can also be a major problem.

I > have measured resistances as low as 10kohm between two traces. As a matter of fact our generator circuit cards have soldermask ( a form of epoxy) applied after wave soldering. Then they are immersed in deionized water and solvent to remove any solder resin. They are then removed from the tank and blown dry with air. They are then baked for 4 hours. The cards are then basically waterproof.

That's at the HIGH setting Mike. Sorry I didn't specify that earlier. No matter what you intimate, our units are rock steady and highly repeatable in relation to using the same water, same volume and wetted electrode depth. > One thing you have in your favor is you are using an op amp as a > comparator.
