The simplest and most effective reservoir monitor you could ever own! The Bluelab Guardian Monitor provides 24 hour continuous reading for pH, conductivity (EC/ppm 700/TDS/CF) and temperature within a nutrient solution.
Designed for indoor use, the Guardian Monitor can be mounted on a wall or hung on a support bar. The Guardian Monitor comes into its own when you are setting up your reservoir with nutrient solution. Place the probes into the reservoir while you are adjusting the water, nutrients and pH, and all you need to do is glance at the large LED displays to see how far away you are from your target. Just adjust and glance.
Not Just an Ordinary Monitor
You have the ability to set high and low alarms, which means that if the solution moves away from the ideal range, the display will flash, alerting you that adjustments are required. As you make the adjustments ensure that the probes remain in the reservoir. When the required levels are reached, the Guardian will automatically go out of alarm state and return to normal monitoring. You will not need to push any buttons or reset the alarm. The Guardian Monitor also has a greater tolerance to FR / electrical interference than other brands.
