Flxa21
The FLXA21 is a 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, it creates a high-precision duplex system for enhanced reliability.
The analyzer continuously monitors detector parameters including impedance, asymmetric potential, and slope, while providing diagnostic status for electrode conditions (dirty, damaged, broken) and low measurement liquid level. This self-diagnosis function significantly reduces maintenance costs and improves operational efficiency.
OpreX is the comprehensive brand for Yokogawa's industrial automation (IA) and control business, representing excellence in related technologies and solutions. The FLXA21 belongs to the OpreX Analyzers family under the OpreX Measurement category.
Supports connection to various pH/ORP, conductivity, electromagnetic conductivity, and dissolved oxygen detectors.
Available in 12 languages: Japanese, English, Chinese, Korean, German, French, Russian, Italian, Spanish, Czech, Polish, and Portuguese.
Compliant with KOSHA, ATEX, and various explosion-proof standards including intrinsically safe types (ATEX, IECEx, FM, CSA, NEPSI) and nonincendive (FM, CSA).
Supports HART, Profibus, and FieldBus communications.
