Fluoride analyzer
Aztec AFM631

Providing safe fluoridation of drinking water.

The Aztec 600 fluoride analyzer provides reliable and highly accurate measurement of fluoride concentrations to enable precise control of water fluoridation.



The Aztec 600 ISE fluoride analyzer measures total solubilised fluoride using a combination fluoride ion-selective electrode.

Featuring ABB's intuitive menu-driven software and the robust ISE sensing system with automatic calibration, users benefit from an analyser that is both simple-to-operate and maintain.

Users benefits from:
  – Continuous measurement using ISE technology
  – Automatic 2-point calibration
  – Buffered measurement for maximum accuracy
  – Low reagent consumption (up to 3 months continuous measurement before reagent replenishment)
  – Temperature-controlled flowcell for measurement stability
  – Intuitive software with full colour graphical display
  – Data logging and graphical process trending
  – Full audit trail capability
  – Secure data archiving to SD Card
