YSI Model 85™ Salinity/Cond/DO/Temeprature

YSI Model 85 Salinity/Conductivity/D.O./Temperature System

A new multi-parameter probe provides simultaneous measurement of temperature, dissolved oxygen (D.O.), conductivity and salinity. No need for separate meters to record accurate D.O. measurements in salt or brackish water.
Specifications: The YSI Model 85 automatically compensates all readings for temperature and will compensate D.O. readings for salinity up to 2.5 times greater than sea water. Unique features of this hand held unit include data storage of up to 50 readings with ID stamp, waterproof construction and simple one button controls. A large, backlit display simultaneously displays temperature along with one of the following parameters: D.O., 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', 25', 50' or 100' cables with combination probe, 6 cap membranes, D.O. fill solution and instruction manual. Power is supplied by six AA batteries, also included. For easier transport, choose the Waterproof Transport Case sold separately.
