PHX pH / ORP Monitor & Controller with Probes
GrowControl™ PHX precision digital pH and temperature monitor with optional ORP, for stand-alone logging or GCX and MPX dosing control.
pH and Temperature Monitor
GrowControl™ PHX is a precision digital pH and temperature monitor, available with an optional ORP (redox) sensor.
Use it as a stand-alone logger, or connect it to a GrowControl™ GCX for centralized data logging, alerts and dosing control.
Stand-alone or Networked
The optional color display and three-button interface add monitoring, alerts and dosing control at the unit.
- Internal memory logs 20,000 data points per sensor, for months or years of storage.
- A real-time clock with battery backup keeps log times accurate through power outages.
- Precision digital electronics with isolated probe inputs read and record the sensor data accurately.
- Download logs to .CSV and graph them on a PC with the LX1 and free software.
