Heavy Duty Nutrient pH Sensor, drop-in / in-line compatible

TrolMaster's new PPH-3 pH probe has been improved in multiple ways. The new PPH-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 PPH-3 has an improved sensor element for more stable and reliable performance. Can be used with the AMP-2 or the AMP-3 nutrient sensor module.
