pH Meter & EC Meter
Measuring the water supply TDS
These tools are to measure the nutrient solution, water supply and the media scientifically and accurately. This is the most crucial and important element in precision farming concept - to be precise in every measurement in order to get a standard and uniform crops quality. TDS (Total Desolved Solids) is to measure water quality before it can be use for plants. You cannot get a reading better than TDS zero when measuring the total amount of dissolved solids in water. As for E.C, it measures the electro conductivity of solutions. In other words, we obtain the concentration of nutrients by using this tool and its the most frequent tool used in Hydroponics, Drip Irrigation or Aeroponics. As for pH meters, please make sure you have a reliable pH meter and know how to calibrate it properly. If your pH drifts off too far, you will find that your plants are not growing as strongly as you would like them to. This has got a lot to do with the availability of Iron in solution. If the solutions or the media is too acidic(whether it is perlite, cocopeat, wood husks etc.), it can actually preventing the roots from absorbing the nutrient resulting a slower growth and low crops yield
