The Orion Star A123 Handheld Dissolved Oxygen Meter is waterproof and portable, it can be powered either by four AA batteries which give over 2000 hours of operation or with a universal power adapter which is sold separately to run on AC power. Icons give quick updates on battery life and completed calibration status plus, the easy to use button layout and onscreen messages help setup menu choices and calibration.
The Orion Star A123 Handheld Dissolved Oxygen Meter has two calibration options to meet procedural requirements: water-saturated air method or a Winkler titration. Automatic temperature, manual salinity input and manual barometric pressure compensation for an accurate result.
