Care & Maintenance
pH meters typically fail due to issues with the probe's glass sensing bulb or reference junction. Proper maintenance extends probe life and ensures accurate results.
Storage Best Practices:
- Always store probe in storage solution MA9015 (never distilled or RO water)
- Fill probe cap with storage solution or calibration buffer before sealing
- Store electrode upright to prevent leakage
- Keep probe hydrated—dry storage damages sensitivity and clogs the junction
- Short-term tap water storage acceptable only if MA9015 unavailable
Cleaning:
- Soak probe in cleaning solution MA9016 for 20 minutes regularly
- Clean more frequently when testing samples with organic material
- Residue buildup impacts sensing bulb sensitivity and clogs the junction
Calibration:
- Calibrate regularly as pH sensing bulbs lose sensitivity over time
- Always calibrate after cleaning or extended storage
- Use electrode diagnostics feature to check probe condition
- Take advantage of 5-point calibration for maximum accuracy
Recommended: Order the Milwaukee pH Maintenance Kit (code PH-Main) at checkout to clean and condition your pH electrode for peak performance and extended lifespan.
