pH & EC Testers

In order to control plant nutrition, it is essential to control the pH level in the nutritive solution.

There are diverse digital and chemical testers for measuring pH. It is also very important to control the food concentration in the nutritive solution. In order to do so, you need an EC tester (electrical conductivity), what allows you to know and to regulate the nutrient content level in the nutritive solution.

It is important to regularly calibrate the digital pH and EC testers by calibration liquids called Buffers in order not to obtain an erroneous reading.
