Yokogawa FLXA21 Modular 2-Wire pH/ORP Analyzer pH Meter
Product information
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 pH/ORP Analyzer with built-in standard calibration table and temperature compensation and stability check functions can perform high-precision pH measurement. It can also measure the temperature and oxidation-reduction potential (ORP) in addition to pH.
The diagnostic function of the sensor constantly measures the impedance, asymmetric potential, slope, etc. and continuously diagnoses the conditions of the sensor, such as the contamination and damage of the electrode, burnout, and a decline in the measured liquid level. In addition, it can save the latest five calibration results and predict the times when maintenance and calibration are needed.
For the wide range of industrial environment, the FLXA21 pH/ORP Analyzer is designed with the enclosure of plastic, stainless steel or stainless steel with corrosion resistant coating.
