This is the Field Mounting DO Probe fro theYSI550A. Instrument not includes.
True Field Performance
Looking for a rugged, field-worthy instrument for measuring dissolved oxygen? The new 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.
Waterproof! Meets IP-67 specificationsField-replaceable DO electrode modules Screw-on cap membranes Over 2000 hours battery lifeCalibrate in either mg/L or % saturation User-selectable temperature units (°C or °F)12, 25, 50, and 100-foot cable lengths Expanded DO and salinity ranges for a wider application rangeThree-year warranty on the instrument and one-year on the DO module and cable!
Packed With Features
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.
