The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, allowing these parameters to be optimized as the crop progresses through each growing phase. A flashing display indicates if a parameter moves away from the desired level, allowing gardeners to make the required adjustments quickly. The Guardian monitors crops 24 hours a day with a built-in alarm system, and also features large, easy-to-read displays with adjustable plant-safe green LED lights, adjustable conductivity and temperature values, push button pH calibration, a silent alarm for both high and low settings, setting retention even during power failure, automatic temperature compensation, and a water-resistant design. The meter ranges are pH from 0.0 to 14.0 with a 0.1 resolution, EC from 0.00 to 5.00 with 0.1 resolution, and temperature from 32 F to122 F (0 C to 50 C) with a 1-degree resolution. The accuracy is ± 0.1 for...

The instrument is only as accurate as the probe is clean. Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller. The probe surface is where the instrument takes the reading of the solution. If the probe face is dirty or contaminated, then the reading will be inaccurate. Accurate readings simplify crop management and provide improved growth. To re-stock your conductivity probe care kit, Bluelab 2.77 EC Conductivity Standard Solution is available in 20ml sachets, and 250ml and 500ml bottles.

Everything you need to clean, hydrate and calibrate pH probes as well as clean and test conductivity (ppm/EC) probes.The instrument is only as accurate as the probe is clean. Accurate readings simplify crop management and provide improved growth. Probe cleaning and correctly storing pH probes ensures you get the most accurate readings possible and will maximize the life of a probe. The probe surface is where the instrument takes the reading of the solution or soil/media. If the probe face is dirty or contaminated, the readings may be inaccurate. Much like the windshield of a car, if it’s dirty you can’t see out! If the probe face is dirty, it cannot read the solution or soil accurately. A tip… if the conductivity reads low, the probe needs cleaning. pH probes specifically, should be kept wet at all times for optimal performance and life.
