Extech FL700 Waterproof ExStik Fluoride Meter

The FL700 is the first truly portable Fluoride meter that is designed for fast accurate measurement of fluoride ions in numerous liquids most commonly drinking water.

The FL700 boast the fastest response time for a meter of its kind at <1min and will accurately compensate temperature automatically the first Fluoride meter to do so.

Users with varying experience can quickly monitor ppm and temperature complete with an analogue bargraph by viewing the built in large LCD display. The FL700 also comes with a handy internal memory capable of recalling up to 25 labelled readings.

Further piece of mind comes from the instruments IP57 waterproof rating and its compliance with EPA method 340.2. (Potentiometric Ion Selective Electrode)

This instrument is commonly used for public water fluoridation control; Fluoride is known to help prevent tooth decay while too much Fluoride is known to be bad for the teeth.
