The YSI 550A-25CC instrument is a dissolved oxygen (DO) and temperature meter for measuring DO in fresh, sea, or polluted water in the field, with a 25’ 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 e...

BioTek recognizes the importance of verifying the performance of analytical instrumentation. Many regulatory agencies and laws such as CLIA 88 and Good Laboratory Practices (GLP) require microplate readers to be checked periodically to ensure they continue to meet factory specifications. Consistent performance over time is a hallmark of BioTek products. However, the consistency must be measured and documented regularly. BioTek's Test Plates are tools that make such testing easy, fast and accurate. By providing a convenient method of monitoring the performance of your reader over time, the Absorbance Test Plate can be an invaluable aid in diagnosing system performance of BioTek's Absorbance Microplate Readers, as well as a documentation tool in your research or clinical laboratory.
