Support of Up to Five Sensors
The FLXA402 can connect up to five sensors, realizing interruption-free measurement even during maintenance. Multiple sensor measurement offers additional functionalities including a variety of calculated data as well as the option to program the analyzer as a redundant system.

Advanced Functions
With the FLXA402, one analyzer can accept: pH/ORP, Contacting Conductivity (SC), Inductive Conductivity (ISC), Dissolved Oxygen (DO), and Optical Dissolved Oxygen Sensors with self-diagnostic capabilities. Additional functions include:
  • Continuous measurement of sensor impedance, asymmetric potential, and slope, and continuous monitoring for electrode contamination/damage, burnout, and a decline in measurement liquid level (ex. pH Analyzer)
  • Online Sensor Wellness checking for predictive maintenance
