【FAQ of AZ8691 Long Probe pH Pen Meter】
Q1: What is the benefit of the AZ8692's ATC feature?
A1: The ATC (Automatic Temperature Compensation) in AZ8692 adjusts for temperature-driven pH fluctuations, ensuring accurate data even if your sample is warmer or cooler than 25°C.
Q2: Why should I choose a long probe pH meter over a standard pen type?
A2: The 12cm long, slender probe is specifically designed for testing in narrow-mouthed containers like test tubes, Erlenmeyer flasks, or deep bottles where standard, bulkier pH pens cannot reach.
Q3: How do I maintain the long probe electrode for longevity?
A3: Always keep the glass bulb moist by adding KCL storage solution to the protective cap. Avoid touching the glass membrane with hard objects and rinse with distilled water after each use to prevent cross-contamination
