In this case, the person is worried most of all by amount of nitrates in the bought delicacies. It is known that nitrates are an obligatory component of mineral fertilizers which are so necessary to grow up a worthy crop.

It is necessary to conduct the measurements only according to the instructions, where admissible norms are specified, as a rule. Irrespective of the model or the producer, the main mission of this useful gadget is an assessment of the nitrates that are in meat, vegetables, and fruit as well as in baby food. This gadget works quite simply: it is necessary to pierce only a studied product with a special probe, which in most cases takes place below the gadget, to receive a result.

Each tester has in advance set standard of the maximum-permissible concentration (MPC) of nitrates. After accomplishing certain manipulations by the device, there is an inscription on the display, specifying the amount of the nitrates that is present in this or that product. For convenience in operating, many gadgets are equipped with special indicators of red, yellow, and green colors, which lit depending on the received result. Modern ecotesters are usually equipped with the soft covers that are capable of saving the gadget from possible damage, casual falling, etc. Besides, they have a simple indicator of the battery charge, which signals from time to time about the need of recharge of a tester.

Today, it is possible to change the situation. This useful development of the scientists, at last, gave people a chance to independently conduct testing for the concentration of nitrates as well as a radioactive radiation. The gadget is available and its cost is rather low and depends on the model.
