As you indicate, the range that we would use the PWT is at the lower end
of the
meter's range. The accuracy, when

Evening Ode,
You made a lot of interesting points about instrumentation.
But using conductivity to get PPM isn't exactly a valid way to do these
things anyhow.
Seems this point has been made before, by you and others.

To a microbe, the silver bullets that don't kill it are irrelevent when

Ken, thanks for the good info, especially on controlling
temperature!
As far

is particularly bad, then we will not achieve this accuracy, and the accuracy of
the meter with normal calibration will also be bad; in short the meter would be
useless for our purposes...

When calibrating, store the meter and solution together for a while so
both solution and the meter are the same temperature.
Don't hold the solution container tightly in your hand because heat soak
from your hand will toss everything out the window.

Mike,
I was on vacation and still catching up on reading
these e-mails, but if you haven't aready could you
please explain how you make your 20PPM like you are
talking about? Thanks in advance!
David
Yes, making good quality cs is not easy, and
making high ppm cs is
much harder. But

Evening Ode,
You made a lot of interesting points about instrumentation.
But using conductivity to get PPM isn't exactly a valid way to do these
things anyhow.
Seems this point has been made before, by you and others.
It's just better than not being able to afford to do it right.

Thank you Mike!
Thank you, Dave. Please let me know if you try this and what kind of
results you get. Ken tried it but wasn't too happy. Not sure why

Can you tell us the exact model number of the Hanna Meter? I have an EC
meter I use for nutrient solutions.
For CS, I rather use the same model that everyone else
