Nitrate tester: specifications, reviews and prices. How to choose a nitrate tester?

Nitrates are a natural component of water and plant foods. These are chemicals that are not dangerous at all. As salts of nitric acid, they enter the body together with food and drink, where they are restored to nitrites. And this new element is nothing but a poison. Nitrites have a negative effect on all tissues and organs of a person, disrupt the work of its immune system, liver, slow down the metabolism.

However, nitrates have a harmful effect on health only when their concentration exceeds the established daily allowance. And this is almost everywhere. The excess of the nitrate level is influenced by modern technologies and quite active use of fertilizers.

There are certain rules according to which all fruits and vegetables must be checked using a professional nitrate test (nitrate meter) before they reach the sales network shelves. However, unfortunately, this requirement is not always met, and the buyer is offered products that are extremely dangerous to health. Is it possible to find nitrates in products independently? Yes. And for this, experts recommend buying a nitrate tester. This is a personal device that will measure nitrates in vegetables and fruits, and do it directly on the market or in the store.

How to choose a nitrate tester? On which device to stop your gaze? Let's consider some features characteristic of such a device.

Digital and Analog Devices

Nitrate tester can show the level of nitrogen salts in products in different ways. So, in analog devices all the measurements obtained are subject to recalculation. Because of the high error, it is impossible to establish the exact content of harmful chemical components with its help. An analog-type nitrate tester has a small memory, which stores no more than nine indicators of permissible standards. The greatest advantage of an analog instrument is its ability to measure the acidity of soils.

The digital nitrate tester is very convenient. It instantly shows the level of dangerous elements without any independent counting. This data is much more accurate than that of an analogue colleague, however, unlike it, a digital nitrate tester is not suitable for measuring the acidity of soils.

Size and weight

What parameters should be considered when choosing a nitrate meter? Specialists recommend paying attention to the appearance of the model. The advantage of any modern device is its lightness and compactness. These are important characteristics that must be taken into account when selecting, as the device will be used in future when visiting markets and shops. A heavy and cumbersome nitrate is unlikely to be appropriate for shopping.

Food

When choosing a nitrate meter, it is important to decide where it will be used. The use of a device operating from a network will be limited only by the home conditions. If the products are checked directly when they are purchased, you will need a nitrate meter with an independent power source. Best if it's a battery. With it, the nitrate meter is charged like a mobile phone. If the device for measuring harmful nitrogen salts works on conventional batteries, it will be expensive to maintain because of the need for constant replacement.

Measurement range

Stopping your choice is recommended on the device that is able to produce results within wide limits. The scale of such a device begins at 0 mg / kg. It should also be borne in mind that the user receives the most accurate measurements of harmful substances when the device records the body weight of a person. This is very important if the products purchased are for children. The safe norm of nitrates is an indicator equal to five milligrams per kilogram of weight.

Functional

When choosing a nitrate meter, the number of measurement programs is also important. That is why before buying you need to determine the list of products in which the level of harmful substances will be measured. As a rule, all models of nitrate-meters give out the results of measurements in fruits and vegetables, fish and meat. This functionality is quite enough for the consumer. However, if you want, you can find devices with a wider list. There are models with additional programs. For example, there is a nitrate tester and a radiation dosimeter (2 in 1).

There are models equipped with a membrane keyboard. It protects the device from splashing water. Some devices are equipped with a backlit LCD matrix matrix display. This function is convenient when using a nitrate meter in bad weather conditions or in nature.

Ease of use

In order to work with the device as comfortable as possible, it is desirable to choose a model that has:

- a minimum of commands and buttons;
- Russified menu;
- a large number of different settings;
- digital submission of results.

Operating principle

The work of the nitrate meter is quite simple. To determine the content of harmful substances in products, each device is equipped with an electronic feeler (built-in or flexible). This sensing element is immersed in the medium under study. If it's a vegetable or a fruit, then the end of the stylus can simply be attached to the cut of the fruit. The sensor is then held until the result appears on the display. In the same way, water is checked. The received information is instantly processed by the device.

However, it should be borne in mind that the distribution of nitrates in vegetables is uneven. For example, in a carrot, most of the harmful elements are contained in its tail, core and tip. On this basis, measurements can give conflicting results. But as for cabbage, the bulk of nitrates is contained in its upper leaves and a stump. In cucumbers, harmful substances accumulate in the skin. All this should be taken into account when using the device.

Cost

Of course, with the increase in the number of functions that a nitrate tester can perform, the price for it, respectively, is growing. For example, devices in memory of which only a small list of researched products are laid, are in the range from 2 to 5 thousand rubles. If the nitrate meter is able to detect the volume of harmful substances among a large number of items, then its price immediately increases to 20-25 thousand rubles.

Variety of models

A few years ago, those who wanted to have household appliances for measuring nitrates in products, the market for such equipment offered a fairly meager range. The list of such products was exhausted only by models of the brand "Soex". This device was a nitrate-tester-dosimeter.

"Soex" is a company that was not the first to discover the level of harmful substances in products. Prior to it, successfully sold products of the firm "Morion". However, the brand "Soex" is known to a wider range of consumers and is the undoubted leader of the market.

For today, consumers can choose for themselves a model from a fairly wide range. So, starting in 2014, Greentest products began to be sold in retail chains. These devices are firmly established not only in Russia, but also, thanks to the use of the latest developments, successfully compete in the world market.

In 2016, the EcoLifePro-2 nitrate meter appeared with a very useful function that allows measuring the amount of salts in water. This device is a Russian manufacturer. Its name in Latin indicates the task of the manufacturer to bring the device to the international market.

Morion nitrate counter

You can purchase devices for measuring the level of harmful elements in products either in specialized retail outlets or in shops operating on the Internet. Among a wide variety of models, sellers also offer the nitrate tester "Morion". To work with this device will not need special skills, and its maintenance will not require special expenses, except for the replacement of batteries.

When buying a nitrate tester must be checked. To do this, you should:

- Install batteries;
- press and do not release the pH button;
- by turning the regulator to the right side, bring the meter needle to the "5" mark;
- release the button and make sure that the arrow has moved to its initial position, standing in front of "0".

What functions does such a nitrate tester perform? Customer feedback confirms the ability of the device to measure the acidity of the soil. Such control is carried out on an abundantly moistened and compacted section of the soil. To measure the acidity, it is sufficient to insert the probe into the soil to a depth of 1.5 cm. The measured values in pH units are indicated by the arrow of the meter.

What else is this nitrate tester capable of? Feedback from users is confirmed by the fact that the device determines the level of human health by its saliva. To obtain reliable results, it is worth remembering that the material for such a study should be taken only on an empty stomach. The saliva is placed in the beaker, into which the probe is inserted. The results obtained will indicate the state of human health and the recommended restrictions in the diet.

However, the main task of the device "Morion" is the product of control for the content of nitrates in fruit and vegetable products. To do this, the probe is injected to a depth of 1.5 cm from the side of the stem. The recorded results should be compared with existing standards.

In addition to all the functions described above, the Morion nitrate meter is able to control harmful elements in plant tissues. Based on the results of measurements, it becomes clear whether nitrogen fertilizers should be introduced as a fertilizer for their future crop.

Nitrotomer "Soex"

The most popular devices on the market for measuring harmful substances contained in food products are the devices of this company. This product is multifunctional and is a dosimeter-nitrate tester (2 in 1). The device operates on a battery that can be recharged from household electricity.

Due to its advantages, the nitrate tester "Soex" reviews consumers deserves, as a rule, positive. This device:
