A cable has a built-in temperature sensor and 2 ports for any combination of pH, ORP, or ISE sensors.
The cable needs to be connected to the ProQuatro or Pro Plus handheld meters.
The YSI 1010 (6051010) is a 2-port (i.e., dual) pH/ORP/ISE cable that ONLY works with the YSI ProQuatro and Pro Plus water quality meters. (Note that the Pro Plus was discontinued and replaced by the ProQuatro.)
The 6051010 is a true field cable with MS (military spec) connectors, a two-year warranty, and a rugged, weighted probe guard. Cables can be ordered in 1-, 4-, 10-, 20-, and 30-meter lengths.
Cables over 1 meter come with the 603062 cable management kit.
*Amplified pH sensors are recommended for cables longer than 20 meters and in applications with very cold water.
