Record accurate and reliable dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion™ Star A213 Dissolved Oxygen and RDO Benchtop Meter, ideal for a wide range of applications and advanced dissolved oxygen analysis in the lab. Use an RDO optical or polarographic DO probe for ultimate flexibility in sensors. Calibrate using water-saturated air, air-saturated water, custom value using Winkler titration or zero point options. Log up to 2000 data point sets with time / date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.
Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO probes or Orion polarographic DO probes Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation Capture your critical readings with measurement stability indicator and selectable read modes – Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals Eliminate the need for magnetic stir bars using the meter-controlled stirrer probe (catalog number 096019) or Orion Auto-Stir BOD probe (catalog number 086030MD) to uniformly mix solutions Data log collects and date/time stamps up to 2000 measurement sets with optional sample ID and user ID Calibration log stores ten most recent calibrations Non-volatile meter memory ensures your data and settings are protected, even with loss of power Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections Flexible power options with universal power adapter or optional AA batteries IP54-rated housing resists dust and splashes and can be wall-mounted if table space is limited Meters include CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty
