QUICK CAL
SOLUTION
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:
Quick Cal Meets USGS
Parameter accuracy guidelines*
pH: at pH 7 ± 0.09 pH units
over range 0-14 pH ± 0.2 pH units
ORP ± 25 mV NA
DO (with stirrer) ± 0.25 mg/L
Conductivity:
Low Range (3 – 50,000 µS/cm) ± 3%
High Range (70 – 200,000 µS/cm) ± 3%

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
