1 4238 ph/redox Measuring range ph 0 to 14 ph Resolution 0,01 ph REDOX ±1500 mv Resolution 1 mv Dual parameter versions available [ph/redox - ph/redox] [ph/redox - Conductivity] [ph/redox - Inductive cond.] [ph/redox - Dissolved oxygen] [ph/redox - Turbidity/SS] ph and REDOX electrodes The electrodes shown below are all of the combined type (Measuring + Reference), do not require maintenance and differ in their structural characteristics, making them suitable for many applications. The elements that must be considered when choosing an electrode are: measuring range, temperature, pressure and chemical substances present in the sample and type of assembly on the system.
