USES: Suitable for various aquariums, hydroponics, laboratories, etc.Electrode caps used for composite electrode test should be kept dry. Avoid cross-contamination between solutions during measurement, so as not to affect the measurement accuracyMaterial: Made of PC plastic, strong and durable, long service lifeCompatible: Suitable for BNC connectors of most pH values and controllersFunction: It is composed of glass glass electrode and silver chloride silver reference electrode. A pH meter is an electronic device used to measure pH. pH value is the concentration of hydrogen ions in an aqueous solution or the activity of hydrogen ions in an aqueous solutionDescriptionThe electrode plug should be kept clean and dry. The external reference solution of the pH electrode probe is a 3NKCL solution. Avoid cross-contamination between solutions during the measurement process so as not to affect the measurement accuracy. Avoid prolonged immersion in acidic fluoride solution. Work in liquids, although special probes are sometimes used to measure the pH of semi-solid materials. Complete pH is a special measuring probe (glass electrode) connected to the human body to measure and display pH readingsFeature:pH Electrode ProbeColor: light blue.Material: PC plastic.Size: 14.5x2x2 cm / 5.71x0.79x0.79 inch.PH Test Range: 0.00-14.00PResponse Time: Le; 1minWorking temperature: 0-60Cable length: 70cm / 27.56inch1 * pH electrode probe
