Meters from economical and simple to robust and modular
High-quality meters are essential to the critical, routine tasks you perform every day. Our portfolio of benchtop and portable dissolved oxygen meters are designed to help you meet your sample analysis challenges with speed and confidence.
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.
