B&CThe constant voltage electrode provided by the company has the following major advantages:
-The measuring and counting electrodes are both made of platinum, which can prevent corrosion from any liquid,
-The reference electrode is gel electrolyte and ring connection, which can ensure good liquid contact and low impedance,
-The electrode is a composite type, which is very easy to clean and replace,
-The electrode can be easily inserted into the flow channels SZ7231 and SZ7233, and the water flow can be relatively stable through the flow channels,
-Both metal electrodes are annular electrodes.
The measuring electrode is located at the top, and the counting electrode is located at the bottom. It is very important to note that the electrodes should not be reversed during installation. The following are the correct installation steps:
It is very important to insert the electrodes into the flow channels SZ7231/SZ7233 in the correct position. If other flow channels are used, it is necessary to maintain a constant flow rate to avoid fluctuations in readings due to changes in flow rate.
