Seeking advice on selecting an online pH electrode for chlor-alkali dechlorination
Thread Content
Our conditions are the same as those before dechlorination in the chlor-alkali industry; we want to test the pH value – any recommendations? 1. How to choose a pH electrode: PVC or polytetrafluoroethylene? Which one to pick? 2. How are domestic online pH meters? How long is the typical lifespan of an electrode? Please help! ! ! Thank you! ! ! :handshake
This requires selecting an electrode that can tolerate the effects of active chlorine, and the most effective option is a potassium chloride-supplemented electrode. There are such specialized ones in the electrodes of DKK. The material for the mounting accessories can be fluoroplastics, CPVC, titanium, etc. Under harsh conditions, it is impossible to accurately predict the lifespan of pH electrodes, as usage conditions and maintenance factors play a significant role.
Our company uses Yokogawa PH meters; they are very good and do not require cleaning. You just need to add potassium chloride
