YSI® ProODO Optical Dissolved Oxygen Meter

Get Readings at Depths in Still Water

With other DO meters, you need to stir the water to get accurate results. With the ProODO, you get accuracy without all the extra work! The optical technology eliminates stirring dependence and frequent membrane changes. There is no warm-up period and no probe fouling by gases like hydrogen sulfide. Plus, you get a greater DO range of 0-500%!

Smart sensors retain their calibration, so you'll only have to calibrate them about once a year. Memory stores 2000 data sets in user-defined fields. Backlit, graphic display is easy to read. USB connection lets you connect to Data Manager software on your PC.

Compliance: IP67 rated.
