Bluelab Meters and Monitors

Understanding the nutrient solution is an important part of successful growing. Growth Technology’s accurate range of Bluelab meters and testing equipment make this task quick and easy.

Bluelab Soil pH Meter

The pH level of soils or substrates strongly influences crop performance. It is important to know what the pH of the soil being used is.

The pH level of soils or substrates strongly influences crop performance. It is important to know what the pH of the soil being used is.

Soil pH measuring made simple!

When measuring the pH level of soil, media or substrates, then the Bluelab Soil pH Meter is the ideal meter. This hand-held meter comes with a Soil pH Probe, Dibber/Auger, pH4.0 and pH 7.0 calibration solutions, plus a helpful Quick Start guide.

Make a hole in the media using the dibber to ensure it is free from coarse particles. Place the soil pH probe into the hole for a direct pH measurement. Soil pH can also be measured by taking soil solution samples.

The Bluelab Soil pH Meter can be used by anybody, from the home-enthusiast, through to more robust commercial applications

Do
  • Rinse the Bluelab Soil pH Probe after each use.
  • Wait for at least 4 minutes for the Bluelab Soil pH Probe to take the soil pH measurement. Soil pH probes are slower to measure than solution pH probes!
  • Clean and calibrate the Bluelab Soil pH Probe when: 1) The reading is different to what was expected. 2) The batteries have been removed or changed. 3) The calibration indicators have disappeared. 4) The Bluelab Soil pH Probe is replaced with a new one or is disconnected from the Bluelab Soil pH Meter.
  • Calibrate the Bluelab Soil pH Probe in fresh calibration solutions. Large bottles of calibration solution should be de-cantered into small plastic containers. This stops contamination of the solution.
  • Use Growth Technology calibration solutions to calibrate the pH where possible. These solutons have been specially created to work with the Bluelab product range. Not all calibration solutions are created equal!
  • Calibrate the Bluelab Soil pH Meter using the pH 7.0 calibration solution first, then the pH 4.0 solution.
  • Be gentle with the Bluelab Soil pH Probe as it is made of glass and is easily broken.
  • Be patient with pH. While calibrating or taking readings, wait until the reading has stabilized to a constant value.
  • Place the Bluelab pH Probe storage cap filled with fresh water or Growth Technology pH Probe Storage Solution back over the tip of the Bluelab Soil pH Probe when not in use. This stops the probe from drying out. If it dries it dies!
  • Insert the Bluelab Dibber/Auger into the soil sample before inserting the Bluelab Soil pH Probe to ensure no damage occurs to the glass probe tip.
  • Remove batteries and disconnect the Bluelab Soil pH Probe if the Bluelab Soil pH Meter is to be stored for long periods of time.
  • Use alkaline batteries where possible.
  • Store in a clean dry place out of direct sunlight.
Don’t
  • Don’t be rough with Bluelab Soil pH Probe or bang it on the side of the tank – it will break!
  • Don’t touch the Bluelab Soil pH Probe tip with fingers. This will contaminate the probe surface.
  • Don’t use de-ionized or distilled water in the storage cap for the Bluelab Soil pH Probe.
  • Don’t rinse the Bluelab Soil pH Probe in de-ionized or distilled water
  • Don’t use rechargeable batteries.
  • Don’t submerse or drop the Bluelab Soil pH Meter into any liquid as it is not waterproof. If it is dropped in to water, immediately remove the batteries and place in a dry warm place for 24 hours.
  • Don’t throw away the Instruction Manual. Keep it in a safe place so it  can be referred back to it if needed. The cleaning and calibration instructions are in the manual and should always be referred to until the grower is confident that the procedure is being carrying out correctly.
  • Don’t open the Bluelab Soil pH Meter – there are no user adjustments inside. This will void the guarantee. It will show if it has been opened!

ph probe is Contaminated – Clean Soil pH Probe

Incorrect Calibration – Ensure calibration solutions are accurate. Replace if in doubt. Wait longer for readings to stabilize before calibrating to a constant value

Calibration unreliable – Calibrate Soil pH probe

Soil pH probe damaged or old – Replace pH probe

This is likely due to a broken glass bulb, tube or connector. Check the Soil pH probe for damage and replace Soil pH probe if necessary.

There is insufficient power to take a reading. Replace the batteries at once. DO NOT use rechargeable batteries.

Likely that the batteries are dead or inserted incorrectly. Check batteries are correctly inserted and replace if necessary

This indicates a problem with the pH calibration. Please read “Section 11” in the BlueLab Soil pH Meter Manual (error message descriptions).

While in pH mode – it is over or under the pH range, therefore the soil is > 14.0pH or soil is < 0.0pH. Check the pH probe connection, if this is connected correctly and problem still arises then the pH probe could be faulty.
