Thermo Scientific Orion STARA3230 Orion Star™ A323 Portable Dissolved Oxygen Meter Only, Parameters: RDO/Dissolved Oxygen/Temp

This Thermo Scientific Orion Star A323 RDO/Dissolved Oxygen Portable Meter is the top choice for testing samples anywhere. It is rugged and dependable, making it ideal for every sample, every day, everywhere. It features a large, backlit graphic LCD display. The informative display shows dissolved oxygen in percent saturation or concentration with temperature and electrode status, time, date, sample ID, user ID and calibration points. Advanced features such as stability and averaging options provide additional options allowing for laboratory accuracy everywhere you need it. It provides ease of use with its plain language screen prompts, soft keys that update for easy selection, and a multi-language interface that supports English, Spanish, French, Italian, German, and Chinese. There is 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™ feature locks in the stable reading on your screen. The ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals. You can calibrate using water-saturated air, air-saturated water, a Winkler titration or zero point calibration. The non-volatile memory holds up to 5000 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 an IP67-rated housing. Three year meter replacement warranty. Certifications: CE, TUV, FCC Class A limits.
