Bluelab Guardian Monitor

The Bluelab Guardian Monitor is a constant indicator of the desired levels of EC, pH and temperature, enabling the grower to optimize these parameters as the crop progresses through each growing phase. A flashing display lets gardeners know if one parameter moves away from the desired level, allowing them 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 0 to 50 degrees Celsius (32-122 degrees Fahrenheit) with 1 degree resolution. The accuracy is ±0.1 for pH and EC, ±1 Celsius (±2 Fahrenheit) for temperature. Protected by two-year manufacturer's warranty. This is a Digtal pH Tester.

With the Guardian monitoring your crops 24 hours a day, with a built in alarm system there is no more test strips or manual meters required, no need to keep checking, less risk of crop failure and less risk of disease due to an imbalance of nutrient or pH levels. You can have peace of mind and ultimately more time in your day!
