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.
 
*All pH probes must be stored by using the storage cap and the correct probe storage solution. If a pH probe gets completely dried out, they will no longer function correctly. Any pH probe returned without the cap and in a "dry" state" will not be eligible for a warranty.
