In this technical overview, we examine the Yokogawa ZR402G zirconia oxygen analyzer converter in action. You'll see how this separate-type configuration works with ZR22G/ZR202G probes to deliver fast, precise oxygen measurements for combustion optimization. Watch as we demonstrate its dual 4-20mA outputs, HART communication capabilities, and IP65-rated rugged design in industrial environments. Learn about calibration procedures, installation considerations, and how this analyzer helps improve combustion efficiency while reducing emissions and fuel costs.
