The YSI 1020 cable assembly (6051020) has a built-in termperature sensor and 2 ports. One sensor port accepts a pH, ORP, or ISE sensor while the second port accepts a dissolved oxygen (DO) sensor. These combination cables ONLY work with the YSI Pro1020, ProQuatro, and Pro Plus water quality meters.

The 6051020 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 include an integrated temperature sensor, however the pH, ORP, ISE, and DO sensors must be ordered separately. The cable needs to be connected to either the Pro1020, ProQuatro, or Pro Plus handheld meter.

The Pro1020 instrument can display DO along with pH or ORP. Sensors available for use with a Pro1020 instrument and a 6051020 cable include the 605101 pH, 605102 ORP, and 605323 amplified pH*. Available DO sensors include 605202 Galvanic DO or 605203 Polarographic DO.

The ProQuatro and Pro Plus multiparameter instruments can display DO, pH, ORP, nitrate, ammonium, and chloride. Sensors available for use with a ProQuatro and a 6051020 cable include the 605101 pH, 605102 ORP, 605103 pH/ORP combo, 605104 ammonium, 605105 chloride, 605106 nitrate, 605323 amplified pH*, and 605324 amplified pH/ORP combo*. Available DO sensors include 605202 Galvanic DO or 605203 Polarographic DO.

*Amplified pH and pH/ORP sensors are recommended for cables longer than 20 meters and in applications with very cold waters.
