The YSI 30 (60530) has built-in temperature and conductivity sensors. These cables ONLY work with the YSI Pro30, ProQuatro, and Pro Plus water quality meters. (Note that the Pro Plus was discontinued and replaced by the ProQuatro.)
The 60530 is a true field cable with MS (military spec) connectors, two-year warranty, and rugged, weighted probe guard. Cables can be ordered in 1-, 4-, 10-, 20-, and 30-meter lenghts. Cables over 1-meter come with the 603062 cable management kit.
Cables come with the sensor built directly into the cable so there is no need to order a conductivity sensor. This combination cable allows for the measurement of conductivity, specific conductance, salinity, total dissolved solids and temperature.
The cable needs to be connected to the Pro30, ProQuatro, or Pro Plus handheld meter.
