1.General Introduction
Yokogawa FLXA202 pH analyzer is a 2 wire modular-designed converter which accepts single or dual sensor measurement, which is applicable for 4 kinds of measurements : pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) with the respective sensor module. For dual sensor measurement, the combination of two same type sensor inputs: pH/ORP and pH/ORP (analog sensor only), SC and SC, and DO and DO are available with two sensor modules. Dual sensor measurement offers additional functionalities; calculated data function and redundant system. Addition to conventional analog pH/ORP sensors, the analyzer FLXA202 can be connected to Yokogawa's digital sensor, FU20F / FU24F / SC25F Digital pH/ORP SENCOMTM Sensor.
