Ideal for critical applications in biopharma and other hygienic industries, VisiFerm sensors eliminate issues like CO2 fouling and the need for electrolyte replacement. Process-related drift due to carbon dioxide and other acid gases is fully eliminated with optical technology. The VisiFerm family includes options like the VisiFerm mA and VisiFerm RS485-ECS, catering to various installation needs and communication protocols. Integrated intelligence with Arc technology enables features like reduced calibration frequency, enhanced diagnostics, and simplified troubleshooting. Explore our range of VisiFerm sensors, designed for reliable and accurate dissolved oxygen monitoring in your controlled environments. Hamilton also provides comprehensive support and resources, including our O2 Measurement Guide and a whitepaper on potential sources of optical dissolved oxygen measurement error and ways to mitigate their impact.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003eThe VisiFerm RS485-ECS optical dissolved oxygen sensor has integrated opto-electronics for full measuring device functionality and self-diagnostics.

The VisiFerm mA is the next generation optical dissolved oxygen (DO) sensor for use in an explosive environment. Designed especially for production environments, the VisiFerm mA is a 2-wire sensor with 4-20 mA standard or digital HART signal output, and ATEX, UKEx \u0026amp; IECEx approval. \u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h3\u003e\n\u003ctable style=\"height: 1004.2px;\" width=\"660\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.6px;\"\u003e\n\u003ctd style=\"height: 40.6px;
