This ORP electrode allows you to connect the 50-ohm BNC socket directly to the input terminal of the ORP meter or ORP controller or any ORP device that has a BNC input terminal. This replaceable ORP electrode gives you the flexibility to measure a solution in a container as far as 200 cm from the device. It precisely determines the redox tension of the intended solution to be measured.

Once your new ORP electrode probe is connected to the electrode input terminal, calibrate it first with the calibration (buffer) solutions before using the newly replace ORP electrode.

This can be used for general water applications such as drinking, domestic and rainwater, aquariums, tanks, ponds, pools, spas, etc.
