Safety instructions

Before using the device, please read all of the safety instructions listed below and pay attention to them when using the device.

Disregard of safety instructions can lead to malfunction or total breakdown of the device. The manufacturer's warranty is not valid if

it is discovered the reason of breakdown because of failure to follow the safety instructions below.

1. Do not connect the device to a computer or USB connector when you are using normal (AAA) batteries. This may lead to

battery fire outbreak or explosion. You should only use the USB connector charger with rechargeable batteries.

2. This device is not waterproof. You should avoid getting the device wet or use it in areas with high humidity. An exception to

this would be when using the device in water quality defining mode. When measuring water quality, you should only dip

the probe in water.

3. You should avoid dropping the device and other physical impacts that can lead to damages to the device.

4. Do not leave the device for exposed to sunlight or high temperatures for a significant period of time. This can lead to

electrolyte leakage from the battery and can cause the device to malfunction.

5. Do not leave the device for long period of time near devices that generate strong magnetic fields. For instance, do not leave

it near magnets and electric motors. Also, keep the device away from places where strong electromagnetic signals are

generated. For example, near radio transmissions.

6. Do not perform measurements in proximity to mobile phones and microwave ovens as this may lead to distortion in the

device's measurement.

7. Do not try to pull apart the device or fix it yourself.

8. When setting up batteries, beware of battery polarity. Incorrect placement of the battery may result in the device

malfunctioning.

Description and device operation

Purpose

SOEKS EcoVisor F4 is designed to:

•perform express analysis of nitrate contents in fresh fruit and vegetables. Nitrate content analysis is based on conductivity

of alternating high-frequency current in the measured product (ionometry).

•measure radiation exposure level and identifying radioactive contaminated foods and construction supplies. Eco Tester can

easily measure the level of radioactivity according to the power level of ion radiation (gamma radiation and beta particles

flux).

•recording of electromagnetic field in facilities, living areas and from domestic appliances. When electromagnetic fields are

detected, electric and magnetic field intensities are evaluated.

•water quality evaluation. The analysis is based on measurement of high-frequency alternating current conductivity.

Nitrate Measurement –Nitrate Tester

Measurement of nitrate content level is based on the patented technology of a biobased product ionometry (Patent of invention №

23 90 767 ionometry. Method for biobased products and the device for its performance) and has been developed by the SOEKS

company.

The technology is based on a specialized procedure method that puts high-frequency electric current through pulp.

Every plant contains ions of potassium, magnesium, ferrum (iron), cuprum, chlorine, plenty of organic acids and other elements in

certain amounts that are necessary for proper growth.

The amount of every single element (ionic or molecular) is determined by bio-organics of certain plant (it has a

basic level of ion concentration) and by contents of water and soil where the plant grows.

People often use fertilization for efficient growth of plants. For instance, saline fertilizers such as nitrates and

phosphates. As they break down and the plant easily absorbs these fertilizers.

As it spreads around the plant, saline ions (nitrates, phosphates and etc.) accumulate in different

plant parts including fruits. This leads to higher amount of electrolytes and to higher electrical

conductivity of fruit as well.

SOEKS EcoVisor F4 has mastered the measurement of nitrate ions content in fruits and vegetables. A percentage of these in fruit and

vegetables is identified by an independent analysis method (potentiometric identification of nitrate content according to Russian

National Standard (GOST) “Fruit and vegetables recycling products. Nitrate content identification”).

The result of express analysis is shown by the device in the form of nitrate ion concentration and its comparison to maximum

permissible concentration for certain product. The device measures the nitrate concentration per kilogram of net product. 200-300

mg of nitrates eaten within 24 hours is considered to be safe for an adult. If 600-700 mg is eaten within 24 hours, nitrates are

considered toxic.

For instance, when measuring a beetroot, the device shows 1000 mg of nitrates per kg. According to the standard measurement, it is

safe to only eat 200-300 mg of this beetroot without damaging your health.

When measuring a watermelon, the device shows 350 mg/kg. If a person eats 2 kg of watermelon, he or she will consume 700 mg

(350 mg / kg x 2 kg) which is toxic.

One should also understand that the shown result is evaluative and cannot be compared to quantified chemical analysis at an

advanced laboratory. That kind of analysis requires a lot of time and is not free. Nevertheless, the presence of such laboratory and

qualified analytical chemist at home is impossible for the majority of people. The EcoVisor F4 is a like portable lab that allows you to

avoid buying suspicious products. This will help protect yourself, your relatives and children from being exposed to these poisonous

products.

The nitrate tester analysis takes only a few seconds. The only maintenance it requires is to change the battery or charge the

accumulator just as you would your mobile phone.

Of course, you may ask yourself is there an increased electrical conductivity if a fruit or vegetable does not contain nitrate ions? This

is possible. But will the consumer feel safer buying a product with increased amount of phosphates or any other ions instead of

nitrates or when buying a product that is already going bad? One should not forget that basic electrical conductivity is determined

for every single type of fresh fruit or vegetable. When a product goes bad, the content and concentration of organic acids change.

ATTENTION! We strongly do not recommend to measure nitrate content in liquids, chemically and heat-treated products,

products that are not included in the device’s menu list. Received data will be misleading and uncertain.

One should also remember that the device is designed for

measuring products at a room temperature. Change of the

product temperature can increase measurement uncertainty. This

regards to products that have just been taken out of fridge or have

been exposed to sun rays. In SOEKS EcoVisor F4 there is a

function of thermal compensation, which is achieved by

means of embedded temperature gauge in probe of the

device. Thanks to software patches, when measuring you

can get the same measurement result even when

temperatures of measured products are different.

After entering the "Nitrate tester" mode. you will see a list of products. You must choose a product

from the list. Press the UP and DOWN icons on the display or press LEFT and RIGHT buttons on

the device to navigate through the menu.

You can confirm your choices by pressing icon of the product in the list or by pressing OK button

on the device. In order to return to main menu, press X icon in upper left corner of the display or

press and hold LEFT button on the device.

After making your choices. the device will perform the product probe calibration.

When calibrating, the probe must not be inserted into product. After

calibration, the device will display the product name, its standard

nitrate content (mg/kg) and recommendations on how to insert the probe.

You must then insert the probe into product, wait until temperature stabilizes (this will be shown

by the indicator in upper right corner of the display screen) and then press MEASURE icon on the

display or OK button on the device once the temperature stabilized.

You may press MEASURE icon at once

without waiting for temperature to stabilize, because

the device will display measurement result anyway. If the product was at

a room temperature, the result will be fairly accurate. In the product has

just been taken out of fridge, the result will be less accurate. In this case,

you may wait for temperature to stabilize and press REPEAT button.

Then, the device will display a more accurate result.

indicator of product's temperature drop.

indicator of product's temperature rise.

In order to get the most accurate result, we recommend inserting the probe for as shown in

the picture.

In order to get the most accurate result, we recommend you wait for temperature to stabilize.
