Meet your regulatory needs with technology that is ideal for a wide range of applications and advanced dissolved oxygen analysis in the lab. Orion advanced and premium benchtop meters offer the flexibility to measure both polargraphic and optical technology. A dedicated kit, complete with BOD stirrer probe needed to fit in a DO bottle for airtight incubation, is available with the Orion Star A213 meter.
Calibrate using water-saturated air, air-saturated water, or custom value, using Winkler titration or zero point options. Log up to 2,000 data point sets with time/date stamp, and easily transfer calibration and data logs via USB or RS232 to a printer or computer when using an Orion advanced or premium dissolved oxygen meter.
