	Each 12 mm electrode includes a FREE electrode saver bottle to extend electrode life
	Use ORP electrodes with meters that read mV to take REDOX readings

Choose a single junction electrode for field, clean water, and general purpose applications. Choose a double junction electrode for most applications, including dirty water, heavy metals and organics applications.

All electrodes have a BNC connector, and are 12 mm dia with a 3 ft cable (except submersible electrode, which is 25 mm dia with a 10 ft cable). We offer many other pH and ORP electrodes for specialty applications; contact us for more information.

IMPORTANT: To take pH readings with Automatic Temperature Compensation (ATC), also order a temperature probe separately below.

Use with all OAKTON pH meters except pH Wand and pH/CON 10
