Product size: total length 135mm, upper outer diameter 9mm, lower outer diameter 5.3mm Features:
1) The factory reference liquid is saturated KCL, and the electrode reference liquid can be replaced as needed. 2) The filling liquid inside the salt bridge: If the solution to be tested is protected, the solution to be tested is placed in the salt bridge; if the reference electrode is protected, the reference is made. The solution inside the reference electrode is placed more stable than the electrode. The salt bridge protects the liquid in the reference electrode from direct contact with the solution being measured. Product exchange: Replace the liquid from the injection port in the middle of the electrode with a syringe. Be careful not to get the mercury ball on it; if the mercury ball breaks, the electrode will break.
Product Warranty: Reference electrode warranty for 2 months, reference electrode average life is 1 year Product Description (mainly summarized):
1. There is a small amount of crystal on the outer wall of the glass tube. This is a KCL solution that slowly leaks in the glass tube. It can be rinsed with water without affecting the use.
2. There should be no air bubbles in the reference electrode, otherwise the electronic measurement circuit will be blocked and the conductive effect will be affected. If there are air bubbles, the finger can be flicked to make the bubble float.
3. The electrode should not be used for the measurement of the medium that reacts with the salt bridge solution. A salt bridge must be added between the electrode and the solution to be tested. In other cases, you don't need to match the salt bridge.
4. Replace the electrode solution with a syringe.
5. When the electrode is not used for a long time, please replace it with a new KCL and store it in the dark.
