- Pencét éta °C/°F ▼ button to toggle between Celsius and Fahrenheit temperature units.
5. Pangropéa
5.1 Kaperawatan Probe
To ensure the longevity and accuracy of your DO probe:
- Keep the probe membrane clean and free from debris.
- Rinse the probe with distilled or deionized water after each use.
- Store the probe properly, typically with the protective cap filled with electrolyte solution, to keep the membrane hydrated.
5.2 Membrane Replacement
The probe membrane should be replaced periodically or if it becomes damaged, scratched, or fouled. Refer to the included spare membranes and the detailed instructions provided with the probe for proper replacement procedures.
5.3 Electrolyte Solution Refill
Ensure the probe is filled with the HI 7042S electrolyte solution. The electrolyte solution needs to be replaced when the membrane is changed or if it becomes contaminated. Refill as needed, following the specific instructions for the probe.
