VisiTrace RS485 L1 Details

VisiTrace RS485 is an optical dissolved oxygen (DO) sensor specifically designed for reliable trace-level oxygen monitoring in brewery and power plant applications. Building on Hamilton's proven optical DO sensor technology, VisiTrace RS485 delivers accurate and stable dissolved oxygen measurements from 0.8 to 2000 ppb, enabling precise monitoring during critical process steps such as filtration, filling, and boiler feedwater analysis.

The sensor is delivered ready to use without the need for polarization, enabling rapid startup and immediate measurement availability. Compared to conventional amperometric dissolved oxygen sensors, VisiTrace RS485 provides flow-independent measurements, fast response times, and requires significantly less maintenance.

VisiTrace RS485 incorporates Hamilton's Arc intelligent sensor technology with an integrated transmitter, enabling direct digital communication and simplified system integration. The sensor communicates via Modbus RS485 RTU for seamless integration into process control systems. The optional Arc Wi Pivot BT enables wireless communication for convenient sensor access, configuration, and monitoring.

The replaceable ODO Cap simplifies maintenance and sensor servicing. The specially developed ODO Cap L1 is designed for trace-level dissolved oxygen measurements and provides resistance against standard disinfectant solutions containing active chlorine and chlorine dioxide. This design enhances durability and ensures reliable long-term operation in demanding brewery and power plant environments.

Combining reliable trace-level measurement performance, low-maintenance operation, and advanced optical sensing technology, VisiTrace RS485 provides a robust solution for long-term dissolved oxygen monitoring in applications where even very low oxygen concentrations are critical.

Common applications Pharma & Biopharma, Bioprocess Upstream, Water, Energy, & Environment, Power Generation, Agri-Food and Beverage

FAQ

Does carbon dioxide sparging impact my DO measurement?

CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed.

FAQ

When should I calibrate my DO sensor?

The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications calibration can be performed before sterilization; however many customers choose to calibrate after sterilization as well.

FAQ

How should I store my optical dissolved oxygen sensor?

Optical DO sensors should be stored in a clean, dry environment prior to use. Avoid prolonged exposure of the inside cap to ambient light to minimize photodecomposition of the luminophore.
