ORP Replacement Probe Hydroponic Electrode Oxidation Reduction Potential Test BNC Q9 Connector Electrode

Features 1. ORP Electrode: It is harmless to the human body and has good conductivity, and widely used in the test of aqueous solutions. 2. Wide Use: For most ORP meters and controllers with BNC Q9 connectors, used in water source systems such as aquariums, hydroponics, swimming pools. 3. PH Test: Measure the pH value in the aqueous solution for accurate up and down adjustment, which needs to be used in conjunction with the meter. 4. Strong Conductivity: The ORP replacement probe is made of sturdy and durable materials, has good conductivity, and is environmentally friendly. 5. ORP Probe: Different water quality ORP ion oxidation degree is always can help remove harmful substances in the water you use to.

After use, you can prepare your own potassium chloride solution. This liquid is the electrode protection solution. Try to keep the electrode well protected with this liquid. 2. Maintenance and precautions for use: a. The saturated potassium chloride inside the electrode tube should be kept at a certain height. (It is necessary to ensure that the silver chloride coating is immersed in the solution.) b. When measuring with the electrode, the test part of the electrode (including the platinum and sand core liquid contact part) must be fully immersed. c. The standard solution of the electrode is a quinhydrone saturated solution. The storage time is 48 hours. (Note: The preparation of the saturated quinhydrone solution: Add excess quinhydrone in the pH 4.00 buffer solution to make it saturated.) The standard ORP potential is 320 mV. d. If the platinum wire of the electrode is contaminated with grease, you can use a cotton swab dipped in acetone or alcohol to gently clean it. If the stained is a non-soluble inorganic substance, you can wipe it with 1 mol/L hydrochloric. You can also wipe the electrode with clean toilet paper every day. 3. If there are unknown crystals on the surface, the ORP electrode will have this phenomenon. It can be cleaned with normal water.4.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
