The YSI 550A dissolved oxygen meter features a waterproof, impact-resistant case and innovative field-replaceable DO electrode modules. Measure dissolved oxygen and temperature simultaneously using YSI's proven polarographic technology for oxygen and YSI Precision TM thermistors, the worldwide standard for accuracy. Measurements are fast and easy with one-hand operation, an easy-to-use backlit display, automatic push-button calibration, and a weighted, quick-sinking probe.
The YSI 550A DO meter has a built-in calibration chamber, low-battery indicator, and salinity and altitude compensation. The new PE membranes are standard with the 550A and provide greatly reduced stirring dependence and faster response times. Additional options with the 550A include 50 and 100’ cables and measurement ranges up to 50 mg/L (500% saturation).
