The YSI 550A dissolved oxygen (DO) meter features a waterproof IP-67, impact-resistant case and innovative field-replaceable DO electrode modules. Measure temperature and DO simultaneously using highly accurate thermistors and YSI's proven polarographic technology for DO. 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, direct salinity, and altitude compensation. The instrument provides simultaneous readings of oxygen and temperature. Dissolved oxygen readings are automatically compensated for temperature.
Screw-on cap membranes make membrane changes easier than ever. The PE membranes are also faster responding and require far less flow dependence. The replaceable electrode decreases any down time due to old or damaged electrodes. Simply unscrew the old electrode, replace it with a new one, and calibrate! No need to send it in or to replace the whole cable assembly. The cables are now even stronger! The meter is shipped in a hard carrying case.
