The FLXA21 is 2-wire module-type liquid analyzer that can be connected to up to two detectors from pH /ORP meters, conductivity meters, inductive conductivity meters, and dissolved oxygen meters.
By connecting two detectors of the same type, a more reliable system can be constructed as a high-precision duplex system.
And the impedance, asymmetric potential, slope, etc. of the detector are constantly measured, and continuously diagnostics status such as the electrode is dirty, damaged, broken and low measurement liquid level.
This self-diagnosis function of the detector reduces maintenace costs and improve OPEX.
OpreX is the comprehensive brand for Yokogawa’s industrial automation (IA) and control business and stands for excellence in the related technology and solutions. It consists of categories and families under each category. This product belongs to the OpreX Analyzers family that is aligned under the OpreX Measurement category.
