Question
What is the difference between PH-1 and PH-2 Underwater Electrodes?
Answer
PH-1 is a One-pole Electrode. PH-2 is a Two-pole Electrode, with a ground electrode and an operation electrode.
Use PH-1 for liquids that contain a large amount of foreign matter. Use PH-2 for liquids that do not contain a large amount of foreign matter because it is more convenient.
