- Warranty A323 dissolved oxygen meter is covered by a 3 year replacement meter warranty
Overview
The Orion Star A323 Portable Dissolved Oxygen Meter is the ideal option for advanced measurement on location. The informative large backlit graphic LCD displays dissolved oxygen in percent saturation or concentration with temperature and electrode status.
Data can easily be updated and transferred using the USB and RS232 ports and complimentary data analysis software. Accurate results are presented with automatic temperature, manual salinity and automatic/manual barometric pressure compensation. The portable handheld DO meter has the capacity to store up to 5000 data points with time and date stamps.
Advanced features such as stability and averaging options with further additional options allow for laboratory accuracy. Calibration can be completed using water-saturated air, air-saturated water, zero point calibration or Winkler titration. Orion polarographic and RDO optical/luminescence-based probes are automatically accepted by the meter meaning they are DO probe compatible. Standard display features include time, date, sample ID, user ID and calibration points. Multilanguage options in English, Spanish, French, Italian, German and Chinese allow for everyone to use this meter.
Readings will not be missed due to addition of AUTO-READ™ which locks stable readings on the screen and the ready indicator alerts when readings are stable. If required, data can be gathered at specific time intervals. The Orion Star A323 Dissolved Oxygen Portable Meter is portable, fully waterproof and housed with IP67-rated protection. Power can be sought either by using batteries which give over 800 hours of operation or powered using the universal power adapter to use AC power.
Included in the package is a 3 year meter replacement warranty.
