OxyGold Dissolved Oxygen Sensors

OxyGold electrochemical sensors are optimized for trace dissolved oxygen measurement in pharmaceutical, microelectronics, and high-pressure applications.

Oxygold g dissolved oxygen sensor

Trace oxygen measurement for pharma, microelectronics, and high-pressure applications.

Hamilton's OxyGold sensors are electrochemical dissolved oxygen sensors designed for precise measurement of trace oxygen levels (parts-per-billion). Applications include pharmaceuticals, microelectronics, boiler feedwater, and high-pressure environments. The OxyGold line features two models: the OxyGold Arc, which incorporates Arc technology with digital outputs (4-20mA, Modbus) and ArcAir software for configuration; and the OxyGold Traditional, which utilizes a VP connector and nanoamp (nA) current output for compatibility with standard controllers and transmitters.

  • The sensors allowed us to improve the end product.

    We have high quality standards and are convinced that Hamilton is able to meet them with its oxygen sensors. We use the oxygen sensors throughout the entire area of ​​beer production and bottling. The sensors allowed us to improve the end product. Hamilton's support is excellent at all times.

FAQ

Do bubbles impact my DO measurement?

DO sensors should be installed away from spargers to minimize the impact of bubbles potentially causing an erratic signal. For ODO sensors, an H2 cap with a convex tip design can be used to mitigate bubble aggregation on the ODO cap.

FAQ

How much torque is needed to install a sensor with PG13.5 threads?

Sensors with PG13.5 threads rely on the o-ring to seal against process pressure. Finger-tight (approximately 2 Newton Meter or 18 inch-lb) should be sufficient to install the sensor without leakage. Additional tightening beyond this can deform the o-ring or strip the threads.

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.
