Hi,
How long is the conductivity fluid good for after it has been open?
Also if the fluid pouch is unopened and expired about 1 year and a half ago, would that cause the probe not to calibrate and not get past step 4 of “Acceptable Range”

Depends on how well you sealed it. If you sealed it airtight with a lighter probably a month. If you just folded it over and clamped it, probably a week tops.
