Bluelab Guardian Monitor Spare pH Probe
Bluelab Guardian Monitor provides 24 hour continuous reading for pH, conductivity (EC/ppm 700/TDS/CF) and temperature within a nutrient solution. Optimizing these critical parameters through a plants’ growing phase helps ensure a successful crop. Designed for indoor use, the Guardian Monitor can be mounted on a wall or hung on a support bar. Set up your reservoir, place the pH and conductivity probes in the solution, then adjust and glance! Simply set high and low alarm states – if the solution moves away from the ideal range, the display flashes. A quick look at the monitor will let you know when your nutrient solution needs adjusting. Plant-safe green LEDs ∙ Large easy to read displays ∙ No calibration required for conductivity and temperature. Simple push button pH calibration ∙ Selectable values for conductivity and temperature. Flashing high and low alarms ∙ Greater tolerance to RF / electronic interference provided. Water resistant design ∙ International power supply included ∙ Replaceable double junction pH probe included. Adjustable display brightness ∙ Non-volatile memory (setting retained when power lost).
