A Precise Automatic pH Monitor, Transmitter, & Logger Built On A Decade Of Proven Technology

AgrowDose™ PHX monitoring systems are autonomous pH set-point systems consisting of a digital PHX hydroponics controller and temperature, pH, and optional ORP or DO probes. Precision sensors and rugged pumps offer reliable and accurate control of reservoirs large and small.

Ideal for applications such as aquarium and aquaponics, pool & spa, or industrial/commercial chemical process monitoring and control. The bright LCD and 3-button interface make this unit capable of operating stand-alone for sensor monitoring, alerts, dosing pump control, and more. Precision digital electronics with isolated probe inputs accurately read and record sensor data.

Internal memory logs 21,600 data points per sensor for months or years of storage. An accurate real-time clock with battery backup keeps log time accurate during power outages.

Combine the PXH controller and an AgrowDose ADi pump to form a powerful and economical automatic MPX dosing system. Operate up to a 4-part dosing pump and store multiple recipes for easy change-over. Learn More here!

Included With The Mini Dosing System:

GrowControl PHX Controller
pH and temperature sensors
OPTIONAL: ORP Sensor

The PHX can be paired with the GrowControl GCX Cultivation Control System for ultimate control of your growing operation. When paired with the GrowControl GCX Controller, you not only gain the ability to control all aspects of your facility's climate and hydroponics systems, but you also gain the option to run your PHX pH system from the comfort of your home with remote access capabilities. Potential problems and issues are sent to you instantly via text or email, too, so you never have to worry!

Agrowtek also offers an easy solution for firmware updates and data logging, using the Agrowtek LX1 AgrowLink. When using the LX1, you can hook your MPX system up to your pc for even more control. Learn more here.

To make sure you set your system up how you truly like and not just how you can get it, Agrowtek systems use standard MODBUS protocols and can be controlled by MODBUS devices using Agrowtek's LX2 ModLink. Learn More Here!

Sensor Set Up & Usage

Connecting Your Sensor Probes To The PHX Controller

pH & ORP sensors are equipped with “BNC” style connectors; push on and then turn to lock in place.

Temperature probes have a screw terminal block. Make the connections according to the label on the transmitter. The terminal block may be removed for easier wire installation or service.

Sensors Require Continuous Contact

PHX systems require the sensors to be continuously in contact with the water to properly manage the dosing pumps. Probe can be located in the reservoir tank, or may be installed inline with a continuously recirculating water flow.

pH & ORP probes must remain wet to avoid damage. Do not allow probe tips to dry!
