Proper cleaning and maintenance of the APERA PH850-FT pH Meter for Surface Measurements is essential to ensure accurate and reliable measurements. Here are the steps to clean and maintain the pH meter:
1. Clean the testing surface: Before taking measurements, make sure the surface you are testing is clean and wet. For example, wet the surface of skin or textiles with distilled water.
2. Connect the electrode: Connect the BNC and RCA plug of the electrode to the input on the pH meter.
3. Rinse the electrode: When measuring, unscrew the bottle cap, pull out the electrode, and rinse it with deionized or distilled water. This step helps remove any contaminants or residues from the electrode.
4. Store the electrode properly: After using the electrode, put it back into the bottle and xxxx the cap tightly. The electrode's measuring tip should be soaked in a soaking bottle containing a certain amount of storage solution. This step keeps the membrane hydrated and the junction unblocked. It is important to note that the electrode should never be soaked in pure water or buffer solution for an extended period.
5. Clean the electrode connector: The connector of the electrode should always be clean and dry. If it gets contaminated, clean it with medical cotton and absolute alcohol. After cleaning, blow dry it to prevent a short circuit of the electrode and slow reaction.
6. Replace the electrode: Every pH electrode will eventually age and fail. The typical service life of Apera pH electrodes is 12-24 months, depending on usage frequency and proper maintenance. It is recommended to replace the electrode every 12-18 months to ensure the best accuracy.
