Điện cực, đầu đo độ dẫn điện của nước hãng Van London
Van London Co. manufactures all types and styles of conductivity electrodes, including laboratory, flow through, and industrial. Featured to the left is our toroidal, or "electrodeless" conductivity probe. The design of the electrodeless conductivity system eliminates any form of polarization, so accurate readings in all types of solutions are possible. Electrode contamination, which can lead to erroneous readings, is also not a problem. The C-PVC encapsulation prevents any solution to metallic contact, thereby eliminating the possibility of gas formations at the electrode surface, which can occur using the more conventional contacting type conductivity systems.
