Standard configuration
One secondary meter, the mounting sheath of immerged (selection), one PH electrode, three packs of standard buffer solution (for PH4.00, 6.86 and 9.18 respectively). |
Ordering guide: |
1. To inform whether the electrode provided is a dual or ternary complex. |
2. To inform the length of the electrode cable (default as 5m). |
3. To inform the installation type of the electrode: flow-through, immerged, flanged or pipe-based
