Combination Multiparameter Meters

YSI 85 Dissolved Oxygen / Conductivity / Salinity / Temperature Meter

The YSI 85 multi-parameter Instrument offers simultaneous dissolved oxygen (D/O), conductivity, salinity and temperature measurements with a single probe to depths up to 100 feet, viewed on a bright backlit display, or stored in a 50 reading memory. Features include automatic push-button calibration, low-battery indicator, automatic temperature (ATC), salinity, and manual altitude compensation, and automatic function check to verify the system is working properly. Auto ranging enables fast, convenient conductivity measurement and the D/O sensor has easy-to-replace screw-on cap membranes. The tough, watertight IP-65 rated case withstands the rigors of field work and includes a built-in storage chamber to protect the probe when not in use. The weighted probe sinks easily and is available with four cable lengths, 10, 25, 50 or 100 feet, and the meter is supplied with a replacement D/O membrane kit and 6 AA alkaline batteries.
