English 2.0 IMPORTANT - Bluelab pH Probe care The Bluelab pH Probe is the only part of the Bluelab Guardian Monitor that should ever require replacing. pH probes DO NOT last forever. They age through normal use and will eventually fail. The life time of a pH probe depends on the environment it is used in and the way that it is treated. To receive a long life from your pH probe, please ensure you follow the guide below. pH probes contain glass and are therefore FRAGILE.
3.0 English 1 2 Select a suitable location that is less than 2 meters from your reservoir, and less than 1.5 meters from an electrical mains outlet. NOTE: Avoid placing the Guardian Monitor where it can be damaged by direct sunlight, water or nutrient salts. Option 1 Mounting keyholes top and bottom Option 1 a) Install two fasteners (top and bottom) to the wall 172mm / 6.¾” apart. b) Slide the Guardian Monitor onto the fasteners using the keyholes.
English 6.0 Power up 1 Switch on power adaptor at the mains. 2 When power is applied the Guardian Monitor will complete a display test sequence. 7.0 Select the desired conductivity unit Conductivity readings can be displayed in EC, CF, TDS or ppm 700. The selected unit is indicated by one of the 3 LEDs next to the conductivity window. When the EC/CF LED is on, the Guardian Monitor is displaying conductivity in units of EC or CF.
English 10.0 Calibration pH calibration is required before first use to ensure that the first reading is accurate. • The Bluelab Conductivity/Temperature Probe DOES NOT require calibration. • The pH of the Bluelab Guardian Monitor DOES require calibration. For accurate pH readings the pH probe is cleaned and recalibrated when: • The reading is different to what you were expecting. • The Guardian Monitor is reset to factory default. • The pH probe is replaced with a new one.
10.0 pH calibration cont. English To calibrate the pH 1 Clean pH probe tip. See section 14.0 (the pH probe does not require cleaning before the first use). 2 pH 7.0 calibration a) Prepare a small amount of pH 7.0 calibration solution in a container. b) Ensure the Guardian Monitor is plugged in and in operation mode. c) Rinse the pH probe tip in fresh water, shake off excess water and place in the pH 7.0 calibration solution. Wait at least one minute for reading to stabilize.
.0 pH calibration cont. pH calibration LEDs English The LEDs next to the pH window will let you know the status of calibration. See the table below. NOTE: The pH probe and hence calibration will eventually fail due to; • Contamination and age of pH probe. • pH probe used to measure solutions at temperatures above 50 °C (122 °F) or below 0 °C (32 °F). • pH probe exposed to aggressive chemicals. • Internal damage to the pH probe from rough treatment.
English 12.0 Set alarms (optional) The alarm function warns you when the solution deviates from the desired levels you have chosen for each measurement. When an alarm condition is present, the display of the affected measurement will flash. If the measurement changes back to within the limits you have chosen, the flashing will stop. Even though the resolution of the Guardian is 10 ppm / TDS, the alarms will set only in 50 ppm and 70 ppm increments.
.0 Set alarms (optional) cont. Turn alarm ON/OFF English Press the alarm button to change between alarm ON and alarm OFF. When the alarm is ON the alarm LED will glow. NOTE: If you press and hold the alarm button you will enter the alarm setting mode. Alarm ‘detailed-set’ To set the detailed ‘alarm HIGH’ and ‘alarm LOW’ values; 12 1 Press and hold the alarm button until ‘AL H’ is displayed in all three windows. 2 Release the button and the current ‘alarm HIGH’ values are displayed in each window.
.0 Cleaning the conductivity/temperature probe Cleaning the Bluelab Conductivity/Temperature Probe English Cleaning the conductivity/temperature probe periodically ensures accurate readings. The conductivity/temperature probe is cleaned using the Bluelab Conductivity Probe Cleaner, or “Jif” a trade name for a liquid scourer cream used in home bathrooms and kitchens. Similar products are called “Liquid Vim”, “Soft Scrub”, “Cif cream”, or “Viss”.
English 14.0 Cleaning the Bluelab pH Probe To ensure accurate readings the pH probe tip needs to be rinsed in water after each use and cleaned prior to calibration using the following instructions. The storage cap must always be put back on after cleaning. Always ensure it contains enough Bluelab pH Probe KCl Storage Solution to cover the probe tip. 1 Remove storage cap from pH probe. Hold the top of the storage cap, twist the cap to loosen then remove. 2 Rinse pH probe tip under fresh tap water.
16.0 Troubleshooting guide Trouble Reason Correction English Contaminated conductivity/temperature Clean conductivity/temperature probe probe. (see section 13.0) . Nutrient reading Temperature of conductivity/ low temperature probe and solution different. Wait 5-10 minutes for conductivity/ temperature probe to reach solution temperature. Temperature of conductivity/ temperature probe different to solution temperature.

Bluelab pH Probe replacement English The Bluelab pH Probe is the only part of the Bluelab pH Meter that requires replacing. pH probes do not last forever. They age through normal use and will eventually fail. To ensure you receive a long life from your pH probe, please read the instructions provided with it.
