FOXBORO 873DO-AIWCNZ Dissolved Oxygen Electrochemical Analyzer – 873 Series Intelligent Transmitter
Imagine a wastewater treatment plant running blind — no real-time dissolved oxygen data, aeration blowers running at full capacity around the clock, biological treatment efficiency collapsing, and effluent quality failing regulatory limits. Or picture a pharmaceutical fermentation batch where oxygen depletion goes undetected, killing the culture and writing off hundreds of thousands of dollars in product. These are not hypothetical scenarios. They are the exact failures that the FOXBORO 873DO-AIWCNZ is engineered to prevent. As a dedicated dissolved oxygen electrochemical analyzer and transmitter, it delivers continuous, accurate DO measurement that keeps industrial processes safe, compliant, and efficient.
Within the Foxboro 873 Series intelligent electrochemical analyzer platform — one of the most trusted process analyzer families in global industrial automation — the 873DO-AIWCNZ occupies the dissolved oxygen measurement position, complementing pH, ORP, and conductivity variants in the same housing architecture. Foxboro (now part of Schneider Electric’s Aveva/Foxboro portfolio) has supplied process analyzers to refineries, power plants, water utilities, and pharmaceutical manufacturers across six continents for decades. The 873 Series represents the mature, field-proven generation of that legacy, widely specified in DCS-integrated process environments where reliability and long-term support matter more than novelty.

Frequently Asked Questions
Q: What does the suffix “AIWCNZ” mean in the 873DO-AIWCNZ model number?
A: Foxboro uses alphanumeric suffixes to encode configuration options such as output type, enclosure rating, approval class, and mounting style. “AIWCNZ” specifies this unit’s exact factory configuration. Contact Konmask.com or refer to the Foxboro 873DO ordering guide for full suffix decode.
Q: Is the 873DO-AIWCNZ compatible with third-party dissolved oxygen sensors?
A: The 873DO transmitter is optimized for Foxboro 871DO series sensors. Third-party sensor compatibility depends on the sensor’s electrochemical type (polarographic vs. galvanic) and connector pinout. Consult the datasheet or contact us for compatibility guidance.
Q: Can this analyzer communicate with a Siemens or ABB DCS?
A: Yes. The 4–20 mA + HART output is a universal industrial standard. Any DCS or PLC with a HART-capable analog input card — including Siemens SIMATIC, ABB 800xA, Emerson DeltaV, and Honeywell Experion — can integrate the 873DO-AIWCNZ.
Q: What is the calibration interval for this analyzer?
A: Foxboro recommends calibration frequency based on process conditions and sensor fouling rate. Typical industrial practice is monthly to quarterly calibration. The HART interface allows calibration to be performed remotely from the DCS without removing the transmitter.
Q: Is this unit new, refurbished, or surplus?
A: Konmask.com supplies new and surplus-new (unused, original packaging) units. Condition is confirmed at time of order. Refurbished units are clearly identified if applicable.
