Trolmaster Drop-in/inline Heavy Duty Nutrient EC/Temp Sensor（PCT-3）TrolMaster's new PCT 3 EC & temperature probe has been improved in several ways. The new PCT 3 features a reduced diameter protective sleeve and threaded body that will allow the probe to be installed into standard 3 4" PVC tee fittings. The PCT 3 also has an improved sensor element for more stable and reliable performance and we have reduced the length of the probe to fit into tight spaces. Can be used with the AMP 2 or the AMP 3 nutrient sensor
