  | | | The Fertometer is a soil tester which measures the level of nutrients in potted plants. It uses a light to indicate whether you should add fertilizer or not. The Fertometer gives a direct fertilizing advise. The Fertometer is an EC-meter which measures the electrical conductivity in potting soil. It will indicate the level of salt content in the pot. Normally you don't know if you should fertilize your house-plants. Now with the Fertometer it will tell you clearly if you may or may not use fertilizer to achieve the very best results! Soil tester for indoor and outdoor container plants. How does the Fertometer work? The Fertometer uses the process of electrolysis and is also referred to as an EC-meter(Electrical Conductivity) in technical terms. The Fertometer works on the same principles as a plant. Like the roots of a plant, it absorbs nutrients from the soil. By measuring the quantity of the absorbed substances, it can be determined whether there are sufficient nutrients left in the soil. These absorbable nutrients are called ions and consist mainly of nitrogen, the principal nutrient for plants during the growing season. All ions are involved in the measurement, to get a good indication of the amount of fertiliser in the pot. It is, though, not possible to recognise from the measurement if a plant is lacking other elements such as potassium or magnesium. An EC-meter reads and interprets an electrical current. This interpretation could be visually represented by an analogue or a digital display. In the case of the Fertometer, a clear and simple indication of the result has been chosen using three lights.
