The YSI 550A-12CC instrument is a dissolved oxygen (DO) and temperature meter for measuring DO in fresh, sea, or polluted water in the field, with a 12’ cable-probe assembly and a backlit LCD to enable reading in dark or dimly lit areas. This microprocessor-based, digital meter has automatic temperature compensation for DO, automatic salinity compensation (0 to 70ppt) for DO, and altitude compensation for calibration. The weighted, quick-sinking polarographic probe has a field-replaceable electrode module and screw-on cap membrane. It runs on 4 alkaline C-cell batteries (included), has a waterproof case with Ingress Protection 67 (IP67), and has European Conformity (CE) certification. DO meters are commonly used in water-quality testing applications.

Dissolved oxygen (DO) meters measure the amount of dissolved oxygen present in water. The amount of DO helps to determine, for example, drinking water quality, the health of lakes or streams, and aquatic organism sustainability. A probe, also called a sensor or electrode, is inserted into the sample to perform the measurement, and the results appear on the meter display. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing.

YSI manufactures instruments, sensors, and software for environmental water quality monitoring and testing. The company, founded in 1948, is headquartered in Yellow Springs, OH.
