Bluelab Guardian Monitor Wi-Fi | pH, EC & Temperature Monitor

Monitor Your Nutrient Reservoir from Anywhere

Take complete control of your hydroponic system with the Bluelab Guardian Monitor Wi-Fi. Designed for serious growers, this professional monitoring system continuously measures the three most important water parameters—pH, electrical conductivity (EC), and temperature—to help maximise plant health and growth.

With built-in Wi-Fi connectivity, the Guardian Monitor integrates with Edenic® software, allowing you to monitor your nutrient solution, receive instant alerts, and adjust alarm settings remotely. Whether you’re at home, at work, or away from your grow room, you’ll always know exactly what’s happening in your reservoir.

Real-Time Monitoring for Healthier Plants

Maintaining the correct nutrient balance is essential throughout every stage of plant growth. The Bluelab Guardian Monitor Wi-Fi continuously displays live readings, making it easy to identify changes before they affect your plants.

Its bright, backlit LED display shows all three measurements simultaneously, providing quick and accurate information at a glance.

Smart Wi-Fi Connectivity

Connect your Guardian Monitor to Wi-Fi and unlock powerful remote monitoring features through Edenic®.

Benefits include:

• View live pH, EC and temperature readings remotely
• Receive instant notifications when readings move outside your preferred range
• Update alarm settings remotely
• Monitor your reservoir from anywhere, anytime
• Gain greater peace of mind while away from your grow room

Designed for Hydroponic Growers

Built and assembled in New Zealand using local and imported components, the Bluelab Guardian Monitor Wi-Fi is engineered specifically for demanding hydroponic environments.

Its durable, water-resistant construction easily handles the everyday splashes and humidity found in grow rooms, while the mains-powered design provides continuous, uninterrupted monitoring.

The monitor can be wall-mounted or suspended above your reservoir, with the included probes remaining permanently submerged for constant readings.

Easy Maintenance

The EC and temperature probes require no calibration, making routine maintenance simple.

To ensure ongoing pH accuracy, the pH probe should be calibrated regularly using Bluelab calibration solutions. For best performance and extended probe life, we recommend using a Bluelab Probe Care Kit for cleaning, maintenance and calibration.
