Bluelab Soil pH Meter Manual

The pH level of soils, substrates or media strongly influences crop performance. Do you know what the pH of your soil is?

pH Soil testing made simple! Most soils have a natural buffer for nutrients and pH, but when it goes wrong, it goes really wrong and fast.

Yellow leaves, stunted growth, slow growth, are all signs that the plant is not getting the nutrients they need from the soil. This is often caused by "lock up". This is a situation where the plant loses the ability to absorb specific nutrient elements because the pH value of the soil is incorrect.

This needs to be dealt with quickly, so the Bluelab Soil pH Meter is exactly what you need. This handheld meter comes with a replaceable Soil pH Probe and instructions for measuring direct into soils or measuring a soil solution.

Used for cropping, pasture, turf culture, containerized plants, home gardens, orchards, tree farms, greenhouses, propagation culture. Anywhere that involves growing plants in soils.

The replaceable soil pH probe can be used to measure the pH value of solutions or nutrient mixes too!

Bluelab Soil pH Meter Questions & Answers

Can I use my Bluelab Soil pH Probe to test the pH of a liquid/solution as well as soil?

Yes you can. However the Bluelab Soil pH Probe will take longer to give you a pH reading because of the way they need to be made.

My pH readings are inaccurate, why?

Possible Reasons:

  • Contaminated pH probe (probe dirty)
  • Incorrect calibration of pH probe
  • Broken glass bulb in pH probe
  • roken stem or connector in pH probe

Possible Solutions:

  • Clean pH probe as described in article below
  • Hydrate the pH probe in KCl storage solution
  • Ensure calibration solutions are fresh and accurate (replace if in doubt)
  • Wait longer for readings to stabilize before calibrating
  • Check the pH probe for damage. If damaged, replace.

What are single and double junction pH probes?

The reference cell of a single junction probe has a wick or frit that makes direct contact with the solution being measured. They are easy and fairly cheap to manufacture but contamination occurs faster in a single junction probe and generally last 6 months. The reference cell of a double junction probe has a wick or frit that makes contact with a second chamber filled with the same material as in the reference cell. This second chamber has a wick or frit that makes direct contact with the solution being measured. Because it has a second chamber, contamination is slowed.
