| Definition | A handheld instrument designed for measurement of salinity, conductivity and temperature in water. It has three operation modes: a) measurement of conductivity without regard to temperature; b) measurement of specific conductance (also known as temperature-compensated conductivity), with adjustable reference temperature set to 25 degC by default; c) salinity calculation based upon conductivity and temperature readings. The probe utilises a cell with four nickel electrodes for the measurement of solution conductance; two of the electrodes are current-driven, and two are used to measure the voltage drop. The measured voltage drop is then converted into a conductance value in millisiemens. YSI Models 30 and 30M operate in the same way, except that Model 30M has a 30.5m cable length and an internal memory capable of saving 50 sets of data. YSI Model 30 can operate within depth ranges of 0 m - 3 m, 0 m - 7.6 m, or 0 m - 15.2 m, depending on cable length; YSI Model 30M operates within 0 - 30.5 m depth. | ||
