About YSI - 6050020 Pro20 Lab/Field Dissolved
The YSI Pro20 instrument is a handheld dissolved oxygen (DO) and temperature meter with graphical backlit display, glow-in-the-dark keypad, rubber over-mold case, military standard connectors, and One Touch Cal feature that calibrates the meter within three seconds. It has on-screen instructions and a selectable language of English, Spanish, French, or German, can store 50 data sets, and has an internal barometer to ensure accuracy. The response time is 95% response in eight seconds with a standard membrane. The meter runs on two alkaline C-cell batteries (included) and is impact-resistant and waterproof, with Ingress Protection 67 (IP67). Additional certifications include Restriction of Hazardous Substances Directive (RoHS), European Conformity (CE), and Waste Electrical and Electronic Equipment Directive (WEEE). The meter is designed for field and laboratory use and is compatible with two different cables. (Cables and probes are sold separately.) The field cable is available in various lengths and has a built-in temperature sensor and a port for the DO sensor (polarographic or galvanic). The ProBOD, a 1m probe/cable assembly designed for lab use, has built-in polarographic DO and temperature sensors, has an AC-powered motor for sample stirring, and fits into a 300mL biochemical oxygen demand (BOD) bottle. 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. What’s in the Box?
