EcoSense DO200M Dissolved Oxygen Meter, DO % Air Saturation: 0 to 200%, DO: 0 to 20 mg/L, Temperature: 0 to 50°C, YSI (CAT#: STEM-AIAE-0017-ZJF)

The EcoSense DO200M Dissolved Oxygen Meter manufactured by YSI offers fast measurement of dissolved oxygen and temperature in wastewater, surface water, and aquaculture applications.
Compared to the EcoSense DO200A, the DO200M features extended memory and simple data transfer with a micro-USB port.
The DO200M calibrates easily in a saturated air environment and displays values in % or ppm (mg/L), giving you the best possible DO data. The DO200M is available with cable lengths of one, four, or ten meters.
The DO200M is also suitable for use in the laboratory with the 200-BOD self-stirring lab probe, making it a true lab and field instrument.
Membrane changes are now easier than ever thanks to screw-on PE membranes. Furthermore, PE membranes have faster response times and are much less dependent on stirring.
