The YSI Salinity, Conductivity and Temperature Instrument is ready to use when you turn it on. A large, backlit display shows temperature along with conductivity, temperature-compensated conductivity, or salinity. In addition, the YSI 30 lets you set the reference temperature and the temperature coefficient if you're measuring temperature-compensated conductivity. The YSI 30 allows for user calibration for highest accuracy. Built-in storage chamber protects the probe when not in use.
The YSI 30M, which stores up to 50 data sets, is also available. The 100 foot cable instrument is automatically a Model 30M when purchased!
