pH Calibration Buffer Table
The temperature coefficient of pH calibration buffers 4.01, 6.86,
7.00,9.18 and 10.01 are stored inside the instrument. The buffers
used to calibrate the instrument must exhibit the same temperature
characteristics as the stored values.

Waterproof
Though the Model H10 meter is housed in a watertight case, DO
NOT use it underwater. The watertight case prevents permanent
damage to the unit if accidentally dropped into non‐corrosive
solutions.
Follow these steps immediately if the unit is immersed in any
solution:
1.
Rinse unit carefully with distilled water. After rinsing and
drying, inspect and clean connectors to remove all
contaminants that may affect probe connections.
2.
Wait for the unit and probe to dry completely before
resuming operation.
3.
If the unit does not function correctly after steps1 and 2, call
ECD for possible repair or replacement (see Warranty).
