Thermo Scientific

Details:

The Thermo Scientific Orion STAR A223 Dissolved Oxygen Portable Meter Kit contains a dissolved oxygen (DO) meter and probe for testing samples anywhere, with automatic temperature, manual salinity, and automatic or manual barometric pressure compensation. The rugged dissolved oxygen (RDO) probe is an optical, luminescence-based probe with 3m cable, stainless steel guard, calibration sleeve, and optical/luminescence-based cap. The meter is calibrated using water-saturated air, air-saturated water, Winkler titration, or zero point calibration. The backlit graphic LCD screen displays DO, temperature, time, date, sample ID, user ID, and calibration information, with prompts in a selectable language of English, Spanish, French, Italian, German, or Chinese. The ready indicator shows when readings are stable.

The memory holds up to 1000 data points with time and date stamp, and measurements can be taken at set intervals. USB and RS232 ports enable data transfer. The meter runs on four AA batteries (included) or on AC power via the universal power adapter (sold separately). The meter housing is waterproof, with Ingress Protection 67 (IP67). Additional certifications include European Conformity (CE), Technical Inspection Association (TÜV), and Federal Communications Commission (FCC) Class A limits. DO meters are commonly used in water-quality testing applications.
