The YSI Model 30 Handheld Salinity, Conductivity, & Temperature System is a rugged, micro-processor based, digital meter with an attached YSI four electrode conductivity cell. The Model 30 is designed for use in field, lab, and process control applications and is available with a cable length of 10 feet.
The large Liquid Crystal Display (LCD) is easy to read and is equipped with a back-light for use in dark or poorly lighted areas.
Though calibration is NOT required, a single calibration will adjust the instrument, regardless of which parameter you wish to read. You can switch back and forth from salinity, conductivity, and temperature compensated conductivity with a single push of the MODE key.
