FX-300-F Inline Reagentless Fluoride Analyzer


Foxcroft inline reagentless fluoride analyzer Foxcroft multichannel inline reagentless fluoride analyzer  

Many drinking water and waste treatment facilities are devoting more money, effort and maintenance than necessary to monitor and control free fluoride levels.

The FX-300-F inline fluoride analyzer features rugged industrial duty ion selective electrodes and reduces the cost of ownership by eliminating sensor tip replacement, maintenance and reagents. Offset calibration with a separate reagent based photometric or colorometric instrument is the only calibration required and is performed without removing the sensor from service.

The system is intended for daily monitoring and process control only.

Modular electronics allow you to purchase only the functions you need, from a single channel fluoride measurement with 4-20mA output only, to a multichannel pH compensated total free fluoride system with alarm relays and control functions.

Additional measurement modules for parameters such as pH, conductivity or ammonium can also be supplied in the same enclosure for multi-parameter monitoring.

The reagentless Model FX-300-F simplifies daily inline free fluoride level monitoring and feed control in 6-9.5pH drinking water or in potable water fluoride removal systems.

The system is available with optional flow panel mounting, everything required is pre-mounted, wired and plumbed on a 1/2" thick 12" x 24" PVC panel. See photos below.

The Model FX-300-F-AS acid service fluoride ion analyzer monitors free fluoride levels in wastewater produced by electronics or semiconductor etching; as well as industrial processes such as stainless steel pickling baths.

Sensors are specially engineered to operate continuously in 0-6 pH solutions; or to withstand acid removal of calcium fluoride and fluorosilicate deposits in higher pH solutions. Submersible, extension tube and valve retractable sensor holders are available for insertion depths into process tanks up to 41”.The acid service sensor cannot be used inline.

 A pH compensation module and pH sensor is available and required to determine total unbound free fluoride ion activity in solutions under 6 pH.
