Product Description

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. A built-in storage chamber protects the probe when not in use.

The calibration is held for long periods of time, reducing costs on calibration solutions. In addition, the sensor requires minimal maintenance but if maintenance is required it can simply be cleaned with the supplied scrub brush.


  • 1-year warranty
  • Rugged weighted probe assembly
  • Automatic temperature compensation
  • Low battery indicator
  • CE compliance
