Bluelab Guardian Monitor
A constant indicator of the desired levels of EC, pH and temperature, enabling you to optimize these parameters as the crop progresses through each growing phase. A flashing display lets you know if one parameter moves away from the desired level, allowing them to make the required adjustments quickly.
It 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, pushbutton 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.
Meter ranges: pH from 0 to 14.0 with a .1 resolution; EC from 0 to 5.00 with 0.01 resolution; temperature from 0 to 50ºC (32–122ºF) with 1º resolution. The accuracy is ±0.1 for pH and EC, ±1ºC (±2ºF) for temperature. Two-year warranty.
