Apera DO803 Luminescent Optical Dissolved Oxygen Probe for Portable Meters

The Apera DO803 Luminescent Optical Dissolved Oxygen Probe is designed as a replacement sensor for the DO850 and DO8500 portable optical DO meters. Utilizing a state-of-the-art luminescent optical dissolved oxygen sensor, it offers significant advantages over traditional galvanic and polarographic probes, including zero oxygen consumption during measurement—crucial for accurate dissolved oxygen analysis in bioprocessing and environmental monitoring.

Key features include:

• Non-consumptive measurement: The probe does not deplete oxygen in samples, eliminating the need for water flow and enabling precise readings in static or slow-moving liquids.
• Rapid stabilization time: Achieves stable dissolved oxygen readings within 1 to 3 minutes, enhancing workflow efficiency in laboratory and field applications.
• Minimal calibration requirements: Calibration process is quick and straightforward, generally requiring only 1 to 2 minutes, supporting routine molecular diagnostics and biomanufacturing quality control.
• Compact design: Probe diameter approximately 0.55 inches (1.4 cm) facilitates integration into various portable DO meters and setups for biotechnological research and clinical diagnostics.

This optical DO probe is essential for applications in biotechnology, including bioprocessing, cell culture monitoring, and synthetic biology research, where reliable dissolved oxygen measurement is critical. It is widely adopted in environmental biology, marine sciences, and biomedical engineering for live-cell viability assessment and dissolved oxygen profiling.
