Accurately measures the pH value of a solution so you know if any adjustments are required.
Plants all need a particular pH to maximize the uptake of nutrient solution. Without taking control of the pH, plants can't take up the necessary elements they need for good strong growth.
The Bluelab pH Meter is the perfect, portable way to accurately measure the pH value of a solution so you can add the right amount of pH up or down to get growth back on track. Simply place the pH probe into the solution and the selected reading is displayed on screen.
As the meter is hand held and does not require a power supply to operate, it can be used anywhere, anytime. Calibration of the pH probe is simple as instructions are supplied on the back of the meter and the easy push button method makes this one of the simplest pH Meters in its class to use.
The pH probe can be purchased as a replacement so you can keep on using the Bluelab pH Meter for years to come.

Bluelab pH Meter with Probe Questions & Answers
Why do I need to measure pH?
It is important to maintain a hydroponic nutrient solution at a pH where elements in the nutrient solution are available to the plants. Each element has a pH range in which its availability is maximised. The range in which most elements are available is between 6.0pH and 6.5pH, but some plants will survive in a range between 5.0pH and 7.5pH. Strong acid (low pH) or alkali (high pH) conditions will upset the balance of the nutrient solution and can cause the loss of nutrient uptake by the plants roots. This can cause "lock up" whereby certain elements become unavailable to the plant.
Why do we need to clean the probes on Bluelab instruments?
A clean probe is an accurate probe!
Cleaning is the most important piece of maintenance required on any Bluelab instrument. The probe comes into contact with the solution and relay the reading back to the instrument for it to be displayed. The probe surface is susceptible to being contaminated or being covered in a greasy film that inhibits an exact reading. There are no shortcuts to cleaning the probes. It is already a very simple procedure and it will also ensure your instrument measures it right every time.
What are pH calibration solutions?
pH probes require calibration periodically to ensure accurate repeatable measurements. Calibration solutions are used to calibrate the probe. These are liquids which are manufactured specific to the calibration process. Bluelab pH products require a two point pH calibration process to ensure the most reliable results.
- If a pH below 7.0 is being measured, use pH 7.0 and pH 4.0 calibration solutions.
- If a pH above 7.0 is being measured, use pH 7.0 and pH 10.0 calibration solutions.
Ensure the temperature of the solution and probe are as close as possible.
