Thermo Scientific Orion Star A223 Portable RDO/Dissolved Oxygen/Temperature Meter

The Thermo Scientific Orion STAR A223 Dissolved Oxygen Portable Meter is a dissolved oxygen (DO) meter for testing samples anywhere, with automatic temperature, manual salinity, and automatic or manual barometric pressure compensation. 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 meter takes a polarographic probe or rugged dissolved oxygen (RDO) optical, luminescence-based probe (probes sold separately).

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 (TÃœV), and Federal Communications Commission (FCC) Class A limits. DO meters are commonly used in water-quality testing applications.

Specifications

Dissolved oxygen (DO) meters measure the amount of dissolved oxygen present in water. The amount of DO helps to determine, for example, drinking water quality, the health of lakes or streams, and aquatic organism sustainability. A probe, also called a sensor or electrode, is inserted into the sample to perform the measurement, and the results appear on the meter display. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing.

Thermo Fisher Scientific manufactures analytical instruments, laboratory equipment, consumables, and software under the Thermo Scientific, Fisher Scientific, and Nalgene brands, among others. The company is headquartered in Waltham, MA.
