SensION+ 9655 is a combination fluoride ion selective electrode (ISE) with an epoxy body, non-refillable, single-junction reference, and non-replaceable crystalline membrane selective to fluoride ions in solution

This electrode requires virtually no maintenance, and it provides fast, stable, and accurate responses in a variety of sample types.

The 9655 has a BNC connector for laboratory use with the Hach sensION+ MM340 GLP pH/ISE Laboratory Meter or the sensION+ MM374 Laboratory Multimeter. The 9655 is ideal for measuring fluoride concentrations in drinking water, wastewater and general water quality laboratory applications.
