| 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 0m - 3m, 0m - 7.6m, or 0m - 15.2m, depending on cable length; YSI Model 30M operates within 0m - 30.5m depth. | |
