The new Trolmaster Heavy Duty Nutrient pH Sensor PPH-3 has been improved and is now drop-in/in-line compatible. The probe features a reduced diameter and threaded body for easy installation in PVC ends. With an improved sensor, it offers more stable performance. Compatible with AMP-2 or AMP-3 sensors.
It is important to store the probe properly to ensure optimal function. If it dries out completely, the probe will not function properly. The pH value will not return when the probe is in a dry state.
