Product Description

Features of FLXA21

High reliability with two detectors and reduced maintenance and instrumentation costs through digital communications

  • pH/ORP, conductivity, and dissolved-oxygen detectors can be connected to two of the same type
  • Backup system with two detectors for higher reliability measurements
  • Achieved reduced installation cost and space saving by measuring two different points
  • Two detectors enable continuous measurement without interruption during maintenance
  • Reducing maintenance/instrumentation costs through HART communications

Improvement of expandability by modular structure

  • Rich system construction by modular structure

Equipped with various advanced functions

  • Self-diagnosis function of the detector
    The impedance, asymmetric potential, slope, etc. of the detector are constantly measured
  • Health and maintenance timing forecasts
    Saves the latest five calibration results and predicts future maintenance and calibration timing
  • Built-in Quick Setup
    Screen instructions (guides) for easy minimal set-up

Touch screen for improved operability and enhanced operation screens

  • Reliable, friendly operation while interacting with the screen
  • Various display modes are available, and a high degree of freedom can be selected.

Sensors suited for a wide range of applications

  • Can be connected to various types of pH/ORP, conductivity, electromagnetic conductivity, and dissolved oxygen detectors

Selectable from 12 languages

  • Japanese, English, Chinese, Korean, German, French, Russian, Italian, Spanish, Czech, Polish, Portuguese

Compatible with KOSHA, ATEX and various other types of explosion-proof

  • Intrinsically safe type of ATEX, IECEx, FM, CSA and NEPSI, and nonincendive of FM and CSA.

Supports communication

  • HART, Profibus, FieldBus

Features of pH and ORP measurement

Built-in calibration standard table, with temperature compensation function and stability check function, realizes high-precision pH measurement.
In addition to pH measurements, temperature and redox potential (ORP) can also be measured.
As a diagnostic function of the detector, impedance, asymmetric potential, slope, etc. are constantly measured to continuously diagnose the state of the detector such as dirt/damage of the electrode, disconnection, and lowering of the measuring liquid level. In addition, the latest five calibration results are stored to predict future maintenance and calibration timing.
