YSI utilizes a high-precision thermistor: 2252 ohms at 25ºC (±1%) for temperature measurement. Resistance changes with temperature and the 6-Series sondes convert resistance into ºC, ºF, or K automatically. Best of all, the temperature sensor is calibration-and-maintenance-free.
Range: -5 to 60ºC
Four pure-nickel electrodes allow the YSI 6560 sensor to accurately determine the conductivity of a sample. Along with conductivity, the YSI 6-Series sonde can calculate specific conductance, salinity, resistivity and total dissolved solids.
Range: 0 to 100 mS/cm
Resolution: 0.001 to 0.1 mS/cm (range
Accuracy: ±0.5% of reading plus 0.001 mS/cm
