pH BUFFER 4

admin_webfirm — Mon, 25 Jan 2016 00:00:00 +0000

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.

pH BUFFER 7

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.

CONDUCTIVITY 2.76

It is essential to calibrate your EC (electrical conductivity) meter with CONDUCTIVITY 2.76 solution regularly. The measurement of available nutrient in the solution is measured as the electrical conductivity. The units used to report the readings are millisiemens per centimetre (mS/cm), Conductivity Factor (cF) or parts per million (ppm).

The conductivity increases with nutrient strength. Distilled or deionised water will give a near zero reading. As a general guide for hydroponics: 1mS/cm = 10cF = 700ppm. Nutrient requirements vary from plant to plant; therefore the ideal conductivity varies from plant to plant also.

pH ELECTRODE STORAGE

Always keep pH electrodes stored in pH ELECTRODE STORAGE solution. 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.

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 Care solutions are made using high Quality Analytical Grade constituents.
