Bluelab Guardian Monitor

In just one glance it magically measures all 3 critical parameters for successful growth; pH, conductivity AND temperature. The Bluelab Guardian Monitor is a constant indicator of the desired levels of EC/ppm 700/TDS/CF, pH and temperature, enabling the grower to optimise these parameters as the crop progresses through each growing phase. The Bluelab Guardian Monitor is mains powered and is mounted to the wall or hung on a support and the probes simply placed into the reservoir. With the Bluelab Guardian Monitor monitoring your crops 24 hours a day and with the ability to set high and low alarms, a flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively. Features • 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 • Temperature compensation • Greater tolerance to RF / electronic interference provided • International power supply • Replaceable double junction pH probe • Adjustable display brightness • Non-volatile memory 2-year warranty (6 months for pH Probe) Do replace the pH probe when it is giving unusual readings or is over 12 months old. pH probes do not last forever and age through normal use and will eventually fail. Do replace the pH probe wetting cap, filled with fresh water or 4.0 pH solution, back over the tip of the pH probe when not in use. This stops the pH probe from drying out. If it dries it dies! Do always place the plastic shroud of the conductivity probe back onto the probe tip after cleaning to protect the probe face and ensure accurate readings. Do wait 5 – 10 minutes for the reading to stabilize if the probe temperature is very different to the temperature of the solution. Don’ts Don’t be rough with pH probe or bang it on the side of your tank – it will break! Don’t touch the pH or conductivity probe tips with your fingers or you will contaminate the probe surface. The only time you can place your fingers on the conductivity probe is when you are cleaning the probe with the liquid scourer. Use a Bluelab Chamois to clean the conductivity probe when available. Don’t throw away your Instruction Manual – keep it in a safe place so you may refer back to it if needed. The cleaning and calibration instructions are in the manual and until you are very familiar with the procedures you should refer back to these to ensure you are carrying them out correctly. Don’t open the Monitor as there are no user adjustments inside. This will void the guarantee.
