Recently, this device has become one of the most popular in the household. Its small size makes it easy to carry to the market and purchase truly safe products. But when buying such devices, you need to consider several nuances
According to sad statistics, more and more gifts of nature, sold in supermarkets and markets, are not environmentally friendly and safe. One of the reasons for this is the large amount of nitrogen fertilizers that were used in the cultivation of crops (calcium nitrate, potassium nitrate, ammonium nitrate). Due to the accumulation of nitric acid salts (nitrates), these vegetables and fruits become harmful and toxic to health.
Decades ago, it was possible to check the presence of nitrates in vegetable crops only in special laboratories. Now it is much easier to do this using a handy device - a portable nitrate meter. Taking it with you to the store or to the market, you can, before purchasing vegetables and fruits, determine the content of nitrates in them and choose those products in which there are at least or no more harmful substances than the norm. It is especially worth purchasing this useful device for those who have small children in their family. But how to choose a nitrate meter? Inexpensive and practical option or more modern, functional, but expensive? The choice is up to the buyer, but it is still worth paying attention to a number of features of the device, which are very important:
Digital or analog?
The advantages of a digital device over an analog one are more than obvious. Measurement data with analog models must be recalculated, since it is problematic to know 100% exactly about the amount of harmful nitrates in a vegetable due to the high error. In addition, the memory of such models can store no more than 9 points of indicators of permissible values. But there are also positive aspects. For example, with the help of such devices it is possible to measure the acidity of the soil, which not all digital analogues are capable of.
Still, digital nitrate meters are more convenient to use and can instantly show the level of nitrates in a kilogram of a vegetable or fruit crop. In this case, the buyer does not need to make additional calculations. The data of such devices is much more accurate. But the range of digital nitrate meters is not as wide as that of conventional ones.
The leader in the production of devices for determining the level of nitrates is the Russian company SOEKS, but there are also many foreign models. Nitrate testers are applicable not only to fruits and vegetables, but also to meat, fish and even baby food. The devices also have additional functions: the ability to add new products to the menu, combine with a computer, select measurements taking into account the age and gender of a person. But the most important criterion is, of course, the accuracy of the device, and then functionality.
Weight and size
Experts recommend paying attention to both the functionality and convenience of the model and its appearance. For any modern device, an important indicator is its compactness and lightness. Therefore, when choosing, it is worth considering these characteristics. Most people want the nitrate meter to be easy to carry and use when shopping for products in the market or in a store. Therefore, a bulky and heavy nitrate meter is unlikely to be suitable for such purposes.
Power supply of the device
An important point that you should definitely pay attention to is the power source of the device. If it can only work from the network, then it is difficult to carry it with you. This option is more suitable for home use. If you plan to purchase a compact mobile nitrate meter for determining nitrates directly upon purchase, then it is better to give preference to a device with independent power supply. But at the same time, it is desirable that a battery is included with it for convenient recharging.
Conventional battery-powered nitrate meters can be expensive to maintain due to the need for frequent replacement, and there are several different types of these appliances on the market today. They can differ in a number of characteristics. In order not to make a mistake with the purchase, it is useful to first read reviews of the most popular models and make up the necessary idea about them. And be sure to check the quality certificates from the sellers.
