YSI® Model 85 Multiparameter Meters

Multiparameter Meters Provide Simultaneous Measurements of Temperature, DO, Conductivity and Salinity

The Model 85 Multiparameter Meters automatically compensate all readings for temperature and will compensate dissolved oxygen (DO) readings for salinity up to 2.5 times greater than sea water. No need for separate meters to record accurate DO measurements in salt or brackish water. Unique features of these handheld units include data storage of up to 50 readings with ID stamp, and simple one-button controls. A large, backlit display simultaneously shows temperature along with one of the following parameters: DO, conductivity or salinity.
For advanced users, an adjustable conductivity reference temperature and compensation factor can be used, as well as user-defined equations for determining salinity. Unit comes complete with your choice of 10' (No. 221295), 25' (No. 221296), 50' (No. 221297) or 100'L (No. 221298) cables with combination probe, six cap membranes, DO fill solution and instruction manual. Power is supplied by six AA batteries (included).
