PPM testers do a better job without the guess work using a TDS tester.

 Interesting statement.  You must not have read much about the meter.
The Hanna information clearly states it measures the TDS.
But goes on to say, it indicates ppm.

>> This is a very accurate meter for colloidal silver PPM testing
This statement from the link, is a bit misleading.

No meter in the world, with a range of 1 to 1999 will have very good accuracy at 10 percent of the full scale range or less. Especially a cheap one. A very expensive meter would be better at the lower limits of the range. Most CS would be a very small percent of the full scale range.

Don't let the statement of "Resolution of 1 ppm" fool you. That certainly does not mean accuracy.

>> Calibration Screwdriver and Calibration Solution.

Of course one calibrates an EC meter, which is what the TDS meter really is, and the ppm meter is a fraud, nothing more, nothing less. I never heard of calibration of a ppm meter. But I have some ideas on that also that may be the best idea yet. Stand by, it will be later.

It does the calculations internally just like everyone does with the calculator.
( I have stated this a few times also )

For a time, I though you posted the wrong link, or did not read it.

 That's close anyway.  ( the price )
   That statement is true.

>> PPM testers do a better job without the guess work using a TDS tester.

I can only deduce that you mean by "guess work", ..... the calculations that people do using other meters. And the different "Scale Factors" they use. Seems many exist.

Mathematics is not guess work, in my book.

So, what are you and others,  "Guessing At" ?

Seems to me, that any fool, that was going to make a sell a meter, mistakenly call it a ppm meter, and sell it for the purpose of using it for CS, it would not have a range of 1 to 1999.

I guess no one at Hanna reads the silver list, ........ or they simply do not know what they are doing.

Hopefully they do not think we are all fools. They certainly misrepresent the facts.

>> PPM testers do a better job without the guess work using a TDS tester.

No if's, buts, or ands, or conditional words in your statement.
Such statements as yours concerns me, because many may believe it.

This is a list of facts, most of the time. <grin>

You quoted my complete message, which was unnecessary but did not say, you did not believe it,
state different ideas, or tell us why, you think it is not true.

I may call Hanna next week and see if they can enlighten me.

I would expect they would be like one tech support I called last week. I stayed on the phone for one hour.

Finally they told me.  "We do not have an answer for your Question".
Of course I understood the problem and the answer, I only wanted to see they would say.

Years back when I worked for a large world wide company, I called my technical support. I realized that the tech support was worthless, I was alone in the world, I had to solve the problem all by myself.

Be more careful, read your links, and don't let the manufacturers confuse or bamboozle you. <grin>
