The Bluelab Guardian Monitor is a top quality meter for measuring pH and EC levels in a nutrient reservoir. It differs from most other meters in that the probes sit in the water, 24 hours a day. The unit screws into the wall and constantly reads the pH, EC and water temperature. At a glance you can see what is happening in the tank and whether you need to do anything. Acting quickly often prevents most issues! Keeping your plants in the sweet spot of pH and EC is a great way of increasing potential yield at the end.
The Bluelab Guardian Monitor features an system that shows too high or too low levels. You can set the tolerances you want and if the reading goes past this, the numbers flash, indicating a problem. As with the Bluelab Combo Meter, the pH probe is replaceable as it is a consumable product. The unit includes a power supply which plugs straight into a UK plug socket.
Main features of the Bluelab Guardian Meter :-

– Simple push button pH calibration.
– Changeable units for temperature and EC.
– Higher tolerance to radio frequency and electronic interference.
