Thermo Scientific Orion STARA2230 Orion Star™ A223 Portable Dissolved Oxygen Meter Only, Parameters: RDO/Dissolved Oxygen/Temp

This Thermo Scientific Orion Star A223 RDO/Dissolved Oxygen Portable Meter makes necessary testing easier. Its durability and dependability make it a great choice for samples every day, anywhere. The large, backlit graphic LCD display shows dissolved oxygen in percent saturation or concentration with temperature and electrode status, time, date and calibration points. Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese. No need to worry about DO probe compatibility – the meter accepts and automatically recognizes Orion polarographic and RDO optical/ luminescence-based probes. Accurate results are easy with automatic temperature, manual salinity and automatic/ manual barometric pressure compensation. The AUTO-READ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable. Calibrate using water-saturated air, air-saturated water, a Winkler titration or zero point calibration. The non-volatile memory holds up to 1000 data points with time and date stamp. Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software. Four AA batteries (included) provide over 800 hours of operation or purchase the universal power adapter (sold separately) to use AC power. Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing. Three year meter replacement warranty. Certifications: CE, TUV, FCC Class A limits.
