Looking for a rugged, field-worthy instrument for measuring dissolved oxygen? The YSI 550A DO features a waterproof IP-67, 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 Temperature 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 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 assmebly. The cables are now even stronger!
