YOKOGAWA FLXA21 Modular 2-Wire Inductive Conductivity Analyzer |
YOKOGAWA FLXA21 Modular 2-Wire Inductive Conductivity Analyzer
The FLXA21 two-wire liquid analyzer offers single or dual sensor measurement. The modular-designed analyzer offers 4 kinds of measurements – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.
The FLXA21 Inductive Conductivity Analyzer performs non-contact measurement according to the inductive measurement principle so that it can be used to monitor the concentrations of acid, alkali and saline solutions in the chemical industry, as well as to measure the conductivity in a wide range of applications in industries such as food, pharmaceutical industry, plating and surface treatment processes, and paper and pulp. In addition, it has matrix compensation and output linearization functions to accurately measure strong acid and alkali solutions. Only one sensor can be connected.
For the wide range of industrial environment, the FLXA21 Inductive Conductivity Analyzer is designed with the enclosure of plastic, stainless steel or stainless steel with corrosion resistant coating.
