Built Tough to Get the Job Done Right

The first thing you’ll notice about the 550A oxygen meter by YSI is its size – small enough to fit in the palm of your hand, the 550A puts everything you need right at your fingertips. What will only become apparent with time, however, is just how tough the unit is. Waterproof to IP-67 standards and housed in a certified high impact-resistant case, YSI dissolved oxygen meters are built for the rigors of real-world field use. All rental units from Environmental Equipment & Supply come with a 100 ft cable attachment.

Powered by Innovative Sensor Technology

What drives the YSI dissolved oxygen meter is its extremely versatile, field-replaceable electrode sensors. A steady state polarographic sensor provides readings as both a percentage and in mg/L and a built-in calibration chamber lets you calibrate to either with the touch of a button. Automatic temperature and salinity compensation ensures readings remain accurate in any condition.
