Meter Maintenance

For pH & conductivity electrodes

"We have not needed to re-calibrate our pH meters for over 3 years!"
Analytical Laboratory

In many situations, Flairform’s electrode cleaner eliminates the need to re-calibrate. Electrode cleaners are usually made from acids, alkalis or chelates. However, these chemicals are largely ineffective for cleaning electrodes that have been contaminated by nutrient solutions.

Flairform Electrode Cleaner is:

• Suitable for both  pH &  conductivity meter electrodes.
• Removes both inorganic and organic contamination.
• Restores electrode accuracy and response time.
• Maximizes electrode life-span.
• Unlike with other cleaners, the electrode does not require ‘rest’ time after being cleaned.
• Easy to use: Soak electrode for 5 minutes.

Dry storage of pH electrodes is the most common cause of pH meter failure in hydroponics!

“pH electrodes last several years when stored properly”

pH electrodes should be stored in a specialized solution when not in use. This helps prevent dehydration of the glass electrode and porous frit (or wick) while preserving the electrode’s filling solution.    pH buffers and distilled water are not suitable for storing pH electrodes as they can upset electrode calibration.  Electrode storage solutions are carefully structured formulations that do not interfere with the chemical composition of the liquid/gel that is contained within the electrode.

Flairform’s pH Electrode Storage helps:

• Maintain electrode accuracy and response time.
• Eliminate reading ‘drift’.
• Maximize electrode life-span.

Conductivity EC/TDS/PPM Probe Care Kit

Everything you need to clean and test conductivity (ppm/EC) / temperature probes

The instrument is only as accurate as the probe is clean. Accurate readings simplify crop management and provide improved growth.

Proper ppm/EC probe maintenance also ensures you maximize the life of the probe and instrument.

The probe surface is where the instrument takes the reading of the solution. If the probe face is dirty or contaminated, the readings may be inaccurate. Much like the windshield of a car, if it’s dirty you can’t see out! If the probe face is dirty, it cannot read the solution.

A tip… if the conductivity reads low, the probe needs cleaning.

You can re-stock your probe care kit with bottles of Bluelab Solutions.

Probe care instructions

• 2 x 20ml single-use Bluelab 2.77 EC Conductivity Standard Solution
• Plastic cup
• Bluelab Conductivity Probe Cleaner
• Bluelab Chamois (conductivity probe cleaning instrument)

Everything you need to clean, calibrate and maintain your pH and conductivity probes.

Care, hydration and calibration – in one kit

Maintaining your Bluelab pH and conductivity probes

To ensure ongoing accuracy and longevity, we recommend that you maintain your Bluelab probes on a regular basis. 

While no calibration is required for conductivity and temperature, you will need to calibrate your pH probe. Your Probe Care Kit contains sachets of pH 4.0, pH 7.0 and KCl solutions for calibrating and storing your pH probes, as well as 2.77 EC standard solution for testing your conductivity probe after cleaning. This kit also includes probe cleaner and cleaning instruments. 

You’ll have everything you need to clean, calibrate and hydrate your probes – in one compact and affordable kit. 

Improve product longevity with regular calibration 

How to calibrate your Bluelab pH products

If you want to improve your Bluelab pH product’s accuracy and longevity, you’ll need to get into the habit of regular cleaning and calibration.  

Luckily, the easy-to-follow calibration process is the same for all Bluelab pH probes and pens.  

After cleaning your pH probe, you’ll need to calibrate it with pH calibration solutions at two reference standards - 4.0 and 7.0 pH. Once calibrated, you can start measuring pH again immediately. You’ll need to recalibrate whenever you clean your pH probe and when your meter alerts you that a calibration is needed.

It is recommended that the electrodes be cleaned regularly with HY-GEN® Probe Cleaner solution. It is recommended that you clean your meter before calibrating or storing it. This will ensure that it operates with accuracy and precision once calibrated. Always keep your pH electrode stored in HY-GEN® pH Electrode Storage solution when not in use.

pH electrodes may show slow response due to the build up of organic and inorganic contaminants which coat or clog them. Regular cleaning with HY-GEN® Probe Cleaner solution can prolong

the life of your meter and maximise electrode performance. HY-GEN® Probe Cleaner solution can also be used to remove contaminants from Conductivity meter electrodes, making this product a worthwhile investment.

pH BUFFER 7 is important as the upper calibration point in the two point’ calibration of electronic meters. Regularly calibrate your pH meter with both pH BUFFER 4 and

pH BUFFER 7 calibration solutions to ensure that your meter is operating with precision and accuracy between pH 4 and 7.

Monitor the pH on a daily basis. As plants grow, demand for nutrients increase. This means the pH can fluctuate and therefore should be tested and adjusted to maintain an optimum working nutrient solution. Nutrient requirements vary from plant to plant; therefore the ideal pH varies from plant to plant also.
