The 6051020 is a 2-port cable that ONLY works with the YSI Pro Plus and Pro1020 instruments. One sensor port accepts a pH, ORP, or ISE sensor while the second port accepts a dissolved oxygen (DO) sensor.
Cables can be ordered in lengths of 1-, 4-, 10-, 20-, and 30-meters. Cables over 1-meter come with the 603062 cable management kit.
Cables include an integrated temperature sensor but do NOT come with pH, ORP, ISE, or DO sensors.
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 605216 amplified pH (kit). Available DO sensors include 605202 Galvanic DO or 605203 Polarographic DO.
The Pro Plus instrument can display DO, pH, ORP, nitrate, ammonium, and chloride. Sensors available for use with a Pro Plus and a 6051020 cable include the 605101 pH, 605102 ORP, 605103 pH/ORP combo, 605104 ammonium, 605105 chloride, 605106 nitrate, 605216 amplified pH (kit), and 605050 amplified pH/ORP combo (kit). 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.
