Q: Why are PPM, TDS, pH and EC important?
A: PPM and TDS are abbreviations that represent the concentration of elements in a solution or atmosphere. PPM is short for parts per million and TDS for total dissolved solids. EC (electro conductivity) is another form of measurement for TDS. PH is a measure of acidity or alkalinity which dictates plant uptake of particular elements.

Q: My Oakton Ecotester pH pen won't calibrate. Is there an easy way to fix this?
A: First, make sure the electrode is kept wet. If it is dry, soak the electrode in storage solution for 24 hours. Always make sure you are using the correct, fresh, calibration solution. Then, make sure the probe electrode is clean and free of any debris. If the pen still won't calibrate within +/-0.1 of the calibration solution(s), try this: Turn the pen off by holding the power button. Turn the pen back on while holding down the HOLD/ENT button. Keep the HOLD/ENT button held down until rSt appears on the screen. Then press the HOLD/ENT button once more. The pen is now reset to factory settings.

Q: My pH meter doesn't hold calibration. How often should I recalibrate it?
A: pH meters do need to be calibrated by the user every day since the membrane does change and is affected by the temperature as well. If pH values are very critical then it will need to be recalibrated several times a day, or before each sample test (depending on how critical the value is). Uncontaminated calibration solution is very important as well. For each calibration, pour some solution in a separate container. Keep out of sunlight and away from heat.

Q: What is the suggested pH range for my hydroponic system and soil plants?
A: Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
