The YSI EcoSense DO200M Dissolved Oxygen / Temperature Meters provides the most accurate data in the most affordable format. The instruments feature an easy-to-use interface, one-hand operation, IP67 waterproof case, and low cost of ownership over the life of the product. The DO200M simultaneously measures dissolved oxygen (% air saturation and ppm) and temperature. With a micro-USB port for transferring data to a PC (no software required), this YSI unit also features a memory that can hold up to 250 data sets. The DO200M is designed for quick, accurate results in an economical platform. The ability to measure DO and temperature in a simple, compact handheld allows the instrument to be used across multiple application sampling strategies from the field to the lab with the optional BOD probe. With a one-year instrument and electrode warranty, waterproof case and ease-of-use, the EcoSense DO200M will fit your needs.
