Bluelab Guardian Monitor Wi-Fi
The Bluelab Guardian Monitor Wi-Fi is one of the most advanced nutrient monitoring systems available, providing 24-hour continuous monitoring of pH, Electrical Conductivity (EC), TDS, PPM, CF, and solution temperature. Designed for both commercial and home growers, this intelligent monitor gives you complete visibility of your nutrient solution while allowing you to remotely monitor your system through the Bluelab Edenic™ app.
Maintaining the correct pH and nutrient concentration is essential for achieving healthy plant growth and maximum yields. Even slight changes in pH can cause nutrient lockout, while incorrect EC levels can result in nutrient deficiencies or fertiliser burn. The Guardian Monitor Wi-Fi continuously tracks these critical parameters, allowing growers to identify problems before they affect plant performance.
Unlike handheld meters that require regular manual testing, the Guardian Monitor Wi-Fi is permanently installed into your nutrient reservoir and continuously displays live readings on its large digital screen. Thanks to integrated Wi-Fi connectivity, you can also view your reservoir conditions from virtually anywhere using your smartphone or computer. The system records historical data, provides trend analysis, and can send alerts when pH, EC or temperature move outside your desired range.
Designed with practicality in mind, the Guardian Monitor Wi-Fi is suitable for recirculating hydroponic systems, run-to-waste systems, aquaponics, aquaculture, and nutrient reservoirs of all sizes. The monitor features plant-safe green LEDs, allowing it to be mounted inside grow rooms without disturbing your plants’ dark cycle. A silent visual alarm warns you when readings become too high or too low, allowing quick corrective action.
Manufactured in New Zealand, Bluelab has over 30 years of experience developing professional water monitoring equipment trusted by growers in more than 100 countries. The Guardian Monitor Wi-Fi continues that tradition with industry-leading reliability, exceptional accuracy, and seamless remote monitoring.
