pH Non-Refillable Electrode Probe pH Test Collection pH Sensor Monitor-pH Non-Refillable Electrode Probe pH Test Collection pH Sensor Monitor-describe 1. Work environment 1. Ambient temperature 5-40 degrees 2. Ambient relative humidity: ≤85% 2. Use, care and precautions 1. Remove the electrode protective cover before the test (the solution in the cover is 3MKCL, if there is crystal exudation, it is a normal phenomenon and it will not affect the use of the electrode ) 2. Observe that the inside of the sensitive bulb is filled with liquid. If air bubbles are found, gently shake the electrode (like a thermometer) to remove the air bubbles from the sensitive bulb, which may affect the accuracy of the test. Calibration and testing of electrodes and pH meters 1. Connect the pH electrode to the input terminal of the pH meter and connect it correctly. 2. Perform calibration according to the instruction manual of the instrument and measure the calibration result. 3. Storage and Care of Liquid-Filled pH Composite Electrodes 1. The electrodes use electrical space. Please rinse the electrode with distilled water and place it in a protective bottle. It will be activated by injecting the solution before the next test. 2. If the electrode is not used for a long time, it should be rinsed and absorbed the remaining distilled water. 3. The sensitive glass bubble on the front of the electrode should not be in contact with hard objects, any damage and scratches will render the electrode ineffective. 4. After a long period of using the electrode, the slope and response speed of the electrode may decrease. The measuring end of the electrode can be immersed in 4% HF for 3-5 seconds or in a dilute HCL solution for 1 to 2 seconds. minutes, then use distilled water containing chlorine Wash soaked in potassium solution (4M) to rejuvenate 5. If there is a sub
