Bluelab Guardian Monitor

The Bluelab Guardian Monitor is a continuous, wall-mounted diagnostic tool designed to track pH, conductivity (EC/CF/TDS/PPM), and solution temperature in real time. Built for hydroponic systems, fertigation reservoirs, and commercial grow setups, this 3-in-1 monitor replaces manual spot-checking with constant visual readouts - helping growers identify and correct drift before nutrient lockout, root stress, or plant deficiencies occur.

Featuring large, high-contrast LED displays, the Guardian allows growers to check critical reservoir parameters from across the room. Programmable high and low visual alarms flash on screen if parameters fall outside set target zones, giving immediate visual alerts even in noisy grow rooms. With factory-calibrated conductivity and temperature probes alongside a simple push-button pH calibration function, setting up and maintaining accurate parameters is straightforward and fast.

Mains-powered for continuous operation, the Guardian Monitor includes long 2-metre probe cables and flexible mounting points to mount easily onto walls, tent frame poles, or support racks. Its splash-proof casing withstands typical grow room humidity and accidental splashes, ensuring long-term reliability for precision climate and nutrient management.

Key Benefits:

• Continuous 3-in-1 Monitoring: Constantly tracks pH, conductivity, and temperature in real time without requiring manual handheld test meters.

• Flashing Visual Alarms: Programmable high/low threshold alarms flash on screen when reservoir parameters drift out of target range.

• Large Backlit LED Displays: Green LED readouts ensure high visibility from a distance and across dark grow tents.

• Factory-Calibrated Conductivity: Conductivity and temperature sensors are factory-calibrated and require no ongoing calibration adjustments.

• Flexible Unit Conversions: Effortlessly toggle display units between EC/CF, TDS, or PPM for conductivity, and °C or °F for temperature.

• Versatile Mounting & Reach: Includes 2-metre probe cables and flexible mounting brackets for walls, posts, and grow tent frames.
