The Autopilot pH-1 controller accurately and reliably measures and controls the pH of any water-based solution, including hydroponic nutrient mixtures, and fish aquarium water.
After selecting the desired pH setting from 5.0 to 8.0 pH, the pH controller measures the pH value of the solution and automatically adds pH adjustment (either acid or alkaline) to change the liquid's pH to the selected level. The pH controller includes a chemically resistant low voltage dosing pump, and both pH, and temperature sensors.
High precision measurement automatically controls pH direction up or down with a simple, user-friendly interface. Features include a digital display, adjustable dosing time, adjustable mixing time, adjustable pH dead band, maximum number of dosing cycles, pH high and low limits, and a data logger which shows the minimum and maximum pH recorded. Never before has there been a pH controller with these features for this value.
Autopilot Digital pH Controller Questions & Answers
What is the suggested pH range for my hydroponic system and soil plants?
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.
My pH meter doesn't hold calibration. How often should I recalibrate it?
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.
