This long version of the pH electrode that has a 50 Ohm BNC type socket allows you to connect directly to the input terminal of the pH meter, pH controller, or any pH device that has a BNC input terminal. Once your new pH electrode probe is connected to the electrode input terminal, you will need to calibrate it using the supplied calibration (buffer) powder. This pH electrode has a longer body, an economical, durable, and quickly provides highly accurate results. 

Many users (i.e. those in clean water treatment, pool and spa water testing, chemical, laboratory, and even some wastewater applications), have their needs met with testers, meters, or controllers that have replaceable pH electrodes.

Works well with handheld meters, testers, or controllers. Re-use the meter portion indefinitely with this replaceable ph electrode.
