SXH Instructions

Built On A Decade Of Proven Technology & Components With New, Enhanced Capabilities To Meet The Growing Demand For Highly Reliable Autonomous Monitoring Applications

GrowControl SXHM precision digital hydroponics sensor transmitter, data logger and mini-controller for temperature, pH, conductivity, plus oxidation reduction potential (Redox, ORP) or dissolved oxygen (DO.) Color display and 3-button interface make this unit capable of operating stand-alone for sensor monitoring, alerts, 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. Accurate real-time-clock with battery backup keeps log time accurate during power outages.

The SXHM hydro sensor continuously monitors the sensor probes and compares the readings to “target” set points for pH, conductivity (EC) and ORP (optional.)

If you are looking to not only monitor your hydroponic set up, but dose on the fly as well, check out the MDX system from Agrowtek. This includes the SXHM monitor, as well as several pump configurations for an easy, autonomous dosing system. Learn more here!

Included With The Mini Dosing System:

  • GrowControl SXHM Controller
  • pH, EC, and temperature sensors
  • OPTIONAL: ORP or DO Sensors

The SXHM 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 & monitor all aspects of your facility's climate and hydroponics systems, you gain the option to run your SXHM doser system from the comfort of your home with remote access capabilities. Potential problems and issues are sent to you at an instant via text or email too, so you never have to worry!

LX1 MDX Connection

If you're looking to use an onsite PC, Agrowtek also offers an easy solution for configuration, firmware updates and data logging, and more using the Agrowtek LX1 AgrowLink. When using the LX1, you can also connect the SXHM to the HX8 8-port hub, which allows the control of multiple dosers, sensors, & relays directly via your onsite PC. 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 protocalls and can be controlled by MODBUS devises using Agrowtek's LX2 ModLink. Learn more here.

Sensor Set Up & Usage

Connecting Your Sensor Probes To The SXHM Controller

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

Temperature and EC 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 for service.

MDX Connection

Sensors Require Continuous Contact

SXHM monitors require the sensors to be continuously in contact with the water in order 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!
