Introduction
The model FL700 is a system specifically designed for the quick and accurate measurement of
fluoride ions in drinking water and other aqueous samples. Unlike other electrode based systems
the FL700 consists of the sensing electrode, measuring electronics, and the display in one
convenient package. This meter is shipped fully tested; with proper use, this instrument will
provide years of reliable service.
Features
Automatic temperature compensation (±10
oC of calibration temperature)
Automatic calibration
Stability sensing to optimize accuracy
Internal Datalogger for storing up to 25 readings
Direct reading of ppm, mV, or mg/l units
Automatic power off after 12 minutes to preserve battery life
Internal error detection
Four separate calibration points available (0.5, 1.0, 5.0 and 10.0ppm)

Electrode Sensor Description
The sensing electrode is a europium doped lanthanum fluoride single crystal
that has been incorporated into a removable sensing module that houses a
reference electrode and temperature measurement system. The high
resistance electrode signals are impedance converted to a low resistance output in the sensing
module to ensure stable and noise free performance.
Reagent Tablets
The FL700 allows the users to follow the ASTM and EPA standard methodology using any of the
TISAB reagents and standards already in use. Also, Extech has developed tablet-form TISAB which
contains all of the essential and approved chemicals that are found in the usual TISAB reagents. A
total ionic strength adjustment buffer (TISAB) is a buffer solution which increases the ionic
strength of a solution to a relatively high level.
The “dry” TISAB reagent does not contribute to sample dilution. The benefits of this method are:
1. No volumetric errors
2. Independent of sample size (± 20% of nominal sample volume)
3. Easy to use in the field or laboratory
4. Can be shipped more easily than liquid reagents
5. Lower cost per test
