YSIŽ 550A Dissolved Oxygen (D.O.) MeterWaterproof to 1 meter—even with the battery door open. - 2,000-hour battery life.
- Rugged aquaculture-grade cable.
- New PE membranes lessen stirring dependence.
This meter is extremely field rugged and sets the standard for aquaculture dissolved oxygen measurement. It is completely waterproof to 1 m (IP67-rated), impact-resistant and measures dissolved oxygen to 50 mg/L and 500% saturation.
It features a field-replaceable, polarographic D.O. probe that is weighted for quick sinking; easy-to-replace cap membranes; push-button calibration; and temperature, salinity (to 70 ppt) and altitude (to 10,000') compensation. The large backlit display shows simultaneous readings of oxygen, temperature (°C or °F), and a low battery indicator. Includes four C batteries.
Three-year warranty on meter, one-year on probe. Spanish manual available.
D.O. Range: 0 to 500% air saturation; 0 to 50 mg/L
Resolution: .1% saturation; .01 mg/L
