YSI 58 DO Meter
The YSI 58 is a proven field and laboratory instrument. The 58 displays oxygen concentrations in two temperature-compensated modes. The instrument offers manual salinity correction, recorder output, and operation from line power or batteries. The case also holds additional batteries for an optional DO field stirrer.
YSI 52 DO Meter
Use the Model 52 in the field with the field-proven 5739 dissolved oxygen sensor and connect a 5905 BOD probe in the lab to complete all of your lab testing. It's as simple as changing cables!
The portable YSI 52 is easy use for field or lab work. Internal memory stores up to 70 readings. An easy to read LCD provides clear, simultaneous display of time, temperature and % and mg/L oxygen. Standard RD 232 port with communications software provides PC with connectivity. Six D cell batteries provide hours of operations. Packaged in a water-resistant case.
YSI 550A DO Meter
Measure temperature and dissolved oxygen simultaneously using highly accurate thermistors and YSI's proven polarographic technology for dissolved oxygen. The fastest DO response times on the market.
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 YSI550A 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 assembly. The cables are now even stronger!
Waterproof, rugged and reliable, the YSI 550A is designed for the field with innovative field-replaceable DO electrodes, over 2000 hours of battery life, CE compliance, a 3-year warranty on the instrument and a 1 year warranty on the replaceable electrodes.
