FAQ
【FAQ of 8694 Sharp Tip pH Pen (Meat/Food)】
Q1: Can I use the 8694 spear tip to directly pierce through tough or frozen food materials?
A1: No. Although the electrode has a sharp "spear" shape, it is made of high-precision glass. To prevent the glass tip from shattering, you should never use it to drill or force your way into hard, frozen, or extremely dense samples.
Always ensure the material is soft enough to be pierced with minimal pressure, or use a separate metal tool to create a pilot hole before measurement.
Q2: How do I clean the AZ 8694’s spear tip after testing meat?
A2: Rinse with distilled water and use a mild detergent to remove fat or protein residues, then dry carefully to maintain accuracy.
Q3: How do I maintain the long probe electrode for longevity?
A3: Always keep the electrode tip 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.
