The ideal pH range for a nutrient solution is typically between 5.8 and 6.5. A pH value above or below this range can increase the likelihood that some nutrients become unavailable to the plant. A pH value of 6.3 typically works well for most plants.

Some electronic meters require a ‘two point’ calibration. pH BUFFER 4 is important as the lower calibration point in the two point calibration process. This will ensure that meters accurately reflect the true reading at the lower end of the range.

SOLUTIONS SCIENTISTS USE
HY-GEN® Calibrations solutions are made according to international standards. The pH ELECTRODE STORAGE and PROBE CLEANER solutions are the same quality as those used in laboratories for the safe cleaning and storage of electronic meters. All calibration and care solutions are made using high quality analytical grade constituents.

HY-GEN® is the mark of guaranteed quality. All formulations and procedures have been prepared under careful supervision by our qualified chemist who has more than 25 years experience.

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.

Always keep pH electrodes stored in HY-GEN® pH Electrode Storage solution. HY-GEN® pH Electrode Storage solution
is the same formula scientists use in laboratories to store glass pH electrodes. pH Electrode Storage solution maximises electrode performance and extends electrode life. pH Electrodes should never be stored dry. Buffers or distilled water are not suitable for storage of pH electrodes. Distilled water will cause ions to leach

out of the glass bulb and render your electrode useless.

The electrodes can become coated in contaminates which build up over time.
It is recommended that the electrodes be cleaned regularly with
HY- GEN® Probe Cleaner solution before calibrating your meter.

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.
