Probe Care & Maintenance
The SE600 probe integrates both pH and EC sensors. Proper maintenance ensures peak accuracy and extends probe life:
Storage: Always store with the cap filled with storage solution MA9015 — never plain water, DI water, or RO water (will damage probe sensitivity)
Cleaning: Soak in cleaning solution MA9016 for ~20 minutes to remove residue and salt deposits
Calibration: Calibrate after cleaning and before each testing session
Technique: Gently stir the probe in the sample for faster, more accurate readings
Recommended add-ons: Order the Milwaukee pH Maintenance Kit (PH-Main) and COMBO-START Kit at checkout for a complete calibration and maintenance solution.
What Customers Say
"Superb meter, easy to use, great customer service."
"Best meter I have ever owned."
"I have owned this meter for almost 8 years and only replaced the probe once. The calibration knobs are easy to use, and even when I am less than gentle with the thing it keeps on going. I wouldn’t consider any other meter."
"Light weight and ergonomic."
