Description

Precise DO Measurement, Less Frequent Calibration. The VisiFerm mA is the next-generation optical dissolved oxygen (DO) sensor designed for explosive environments. This 2-wire sensor features 4-20 mA and digital HART outputs for seamless integration into production processes. Now carrying full CSA certification alongside existing ATEX and IECEx approvals, the VisiFerm mA offers a truly global solution. It meets all CSA, UL, and FM requirements for intrinsically safe process control in hazardous locations across North America (Class I, II, and III).
The VisiFerm optical technology improves the measuring performance and simplifies maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid startup with no polarization time, and no nA noise. It requires less maintenance than an amperometric oxygen sensor as it does not have a mechanically sensitive membrane or a corrosive electrolyte. The VisiFerm mA mitigates the negative effects of aging, temperature, and photobleaching to reduce the frequency of calibration and deviation reports.
