APPLICATION
A calibration standard of an appropriate chemical composition to perform a one-
point calibration of all four MP TROLL Basic sensors (pH, ORP, Conductivity,
Polarographic Dissolved Oxygen) at the same time with a single solution. Four
250 mL containers, each sufficient for at least 2 Quick Cals.
Shelf Life, unopened
6 months
After opening
7-21 days
EXPECTED ACCURACIES
The following accuriacies may be expected when calibrating the MP TROLL
using Quick Cal solution and following instructions in the Win-Situ Quick Cal
Wizard and/or in the MP TROLL Operator's Manual:
GUIDELINES AND PRECAUTIONS
•
Store the solution cool and dark. Shake well before use. For best results,
calibrate at the temperature expected during field use
•
Do not store sensors in Quick Cal solution
•
For best results, use fresh solution for each Quick Calibration
•
Dispose of used solution by flushing down the drain with plenty of water
•
Solution is best if used before date on bottle, but may be usable beyond that
date if stored cool, dark, and tightly capped
