 This pH meter allows you to measure pH, absolute mV, relative mV or temperature, select one of three sets of standard buffer groups, and standardize with up to 5/6 buffers.
+To use this tool, please ask one of our staff for help (located in a locked cabinet beneath the Bambu Printer). The buffers are located in Chemical Storage Cabinet #4.

   - Repeat steps 3-6 with the pH 10 (blue) buffer solution. When the meter accepts the second , pH 10, buffer solution, it will briefly display the percent slope associated with the electrode’s performance prior to returning to the Measure mode. If the electrode is within the range of 90 – 102%, the GOOD ELECTRODE message will appear.

+  - Immerse electrode into solution and stir moderately.
+  - When the meter senses that the reading has stabilized, the stable icon will appear under the reading. This message will not appear if the stability indicator has been turned off during setup.
+  - You can save your reading to the meter’s memory using the save key.
