  Thermo Scientific AF7 Coulometric Titrator



Utilizing the extremely accurate technique of iodine generation, the Thermo Scientific Thermo Scientific AF7 coulometric titrators takes moisture measurement to new limits of accuracy and performance within a wide measuring range of 1 ppm to 100% H2O. 


   Product Detail


  • Fastest Coulometric Titrator - 20,000 micrograms (20 mg) of water titrated per minute - (high current mode)
  • Completely Sealed Chemical Handling System - integral pump controlled from keypad, easy, safe replenishment of reagents without opening vessel to environmental humidity
  • Instrument monitoring of anolyte/catholyte life - detecting and current generating electrodes, no need for operator monitoring
  • User-prompted methods - simple YES/NO or numeric data entry

The Thermo Scientific AF7 is the universal answer for the widest range of moisture analysis, offering coulometric accuracy and precision at volumetric titrator speed.  You can even use the same sample size as you would for a volumetric titration.  The AF7's flexibility is reflected in it's ability to perform coulometric titrations at both low and high currents.  The AF7 titration vessel has exceptionally large-area platinum electrodes which, when used with high conductivity reagents, provide the current necessary to operate at the titration rate of 20 mg per minute analysis of water, the typical rate of volumetric titrators.
