The Bluelab Guardian Monitor is a continuous indicator of EC, pH and temperature values that allows you to optimize these parameters as the crop progresses.

Finally, and thanks to technological advances, the Bluelab Guardian monitor has an accurate, robust and easy-to-use multi-parameter monitor to measure three critical values for the grower.

How should we place the probes of the Bluelab Guardian Monitor?

The pH and conductivity / temperature probes of the Bluelab pH meter must be immersed in the liquid to obtain the measurement.

There is the option of placing a suction cup holder on the pH probe, which we will place on the side of the tank where the liquid we are going to measure is, to prevent it from being damaged.

Once we have placed the pH probe, we insert the conductivity / temperature probe, and the measurements will begin to appear on the screens.

Main features of the Guardian Monitor Bluelab:

• Large “Plant Safe” display with green LEDs to prevent any stress

• Measures temperature from 0 to 50 ºC / 32 to 122 ºF
• Selectable values for both EC and temperature
• Single button pH calibration
• No EC or temperature calibration required
• Silent (visual) alarm for high and low values
• Retains programmed values even if the power goes out (non-volatile memory)
• Automatic temperature compensation
• Water resistant (splash)
• 2 years Bluelab warranty (6 months warranty on the electrode)
• Adjustable screen brightness
