To get acquainted with your new EcoLife PRO-2 nitrate meter’s internal design and rules of operation
(correct use, technical service, repair, storage and transportation) please read the supplied manual carefully.
EcoLife PRO-2 nitrate meter is a hand-held device, produced to measure the quantitative nitrate
content (rapid analysis) in fresh fruits, vegetables, meat and infant food. The device also can be used as
salimeter (TDS-meter) that measures the concentration of water-insoluble inorganic impurities (the salts of
different metals generally).
The nitrates are the nitric acid salts (NO3), contained in the soil and absorbed by the plants from the
soil. Thanks to their positive influence on the crops growth and fecundity, and the harvest ripening speed,
nitrates are widely spread in agriculture. When getting into human body, nitrites react with its microflora
and transform into nitrites (NO2). The nitrites are absorbed into the blood stream from the intestinal tract
and having aggregated with hematoglobulin form methylhemoglobin. Methylhemoglobin is a stable
chemical compound that doesn’t transport oxygen. It induces hypoxia, accumulation of lactic acid in tissues,
tissue intoxication and histolysis.
However most researchers today believe that the cancer is the main danger, especially the gastro-
intestinal cancer. With the nitrites, cancerigenic nitrate amides and amines can be synthesized from almost
any food both in stomach and intestinal tract.
Attention! Please note that the measuring results of the present device cannot replace chemical
analysis performed in a professional laboratory. The product is not intended for professional use in the field
of national metrological monitoring. The data measured by it cannot be used for making official reports on
the nitrate concentration in fresh fruits, vegetables, meat and infant food.
Attention! The device is intended to measure nitrates in fruits, vegetables, fresh meat and infant food
only. Sausage, ham and gammon, etc. contain chemical compounds used for smoking, coloration, etc. that
invalidates the measurement!
Attention! Manufacturer reserves the right to make changes in the list of testable foods without
previous notice!
Attention! After storing the product in a cold place or transporting it in winter you should keep the
device at room temperature for 2 hours before operating.
Attention! Please request to perform functional testing before purchase. Also make sure that the
warranty sticker placed into the battery compartment is not damaged. Check the delivery set against article
1.3.1 of this manual. Ensure the warranty card is signed, dated and stamped.
Attention! Read this manual carefully in order to use the product efficiently and safely for a long
time.
Follow the rules, restrictions and instructions contained in the manual to increase the lifespan of the
equipment and to use it most effectively.
The manufacturer's warranty will become invalid prematurely if the user of the equipment does not
follow the storage and transportation instructions.

1 SPECIFICATION AND OPERATION
1.1 Intended usage and operation area
1.1.1. EcoLife PRO-2 nitrate meter is produced to measure the quantitative nitrate content (rapid
analysis) in fruits, vegetables, fresh meat and infant food. The product’s working principle is based on
measuring the electrical conductivity of fruits, vegetables, fresh meat and infant food.
The device also estimates the quality of water used for domestic and technical purposes from different
sources (streamline filters, pitchers, water wells, etc). When measuring the water hardness level (level of
general water salinity), the measurements of ppm (particles of dissolved substance per million particles of
water) are performed by the device.
1.1.2. The software of the equipment provides:
original algorithm of measuring the quantitative nitrate content in foods and the salt content in
water;
indication of the quantitative nitrate content in tested food together with the indication of the
maximum allowable concentration (MAC);
indication of the battery charge level;
indication of current date and time;
storing the history of testing that can be reviewed.

1.4.2. The product provides measuring and indicating of quantitative nitrate content in foods and salt
content in water. The product also provides indicating of additional information that includes:
- data (day, month, year);
- current time (hours, minutes);
- battery charge level.
1.4.3. Device control:
- Power button («ПИТАНИЕ») allows to switch the device ON and OFF (by long-term pushing
of the button) and return to the Food group list (by short-term pushing of the button);
- Setup button («НАСТРОЙКИ») allows you to switch back and forth from the Setup menu;

- Button box allows to navigate through the Settings menu and food groups’ items lists and
select values;
- Measurement button («ИЗМЕРЕНИЕ») allows you to switch to the Measurement mode;
- History button («ИСТОРИЯ») allows to display the history of testing.
1.4.4 The power is carried out by two AAA batteries. Please see how to install batteries into enclosure
on the battery compartment bottom and in Picture 3.
Picture 3 – Batteries installation scheme
Note. You can use accumulators of the same type instead of batteries. In this case charge the
accumulators by yourself using the external power supply.
2. Correct use

2.2.2. Measuring procedure
To switch the device on press the button and keep it pressed down for 2 seconds. When you do,
you’ll see the screen saver shown in Picture 4.
Picture 5 – Screen saver
The Food group selection window opens. The chosen food group flashes green (see Picture 5).
Navigating through food groups and confirming the choice of a food group are performed by the button
box .
Picture 5 – Food group selection menu
Pressing the buttons or moves the user into one of the four food groups’ menus (vegetables,
fruits, foods, salimeter) (see Picture 6). For navigating through the list use the buttons (up/down
arrows are for moving the cursor up and down in the list; left/right arrows are for navigating from page to
page). Short-term pushing of the button returns you to the Food group selection menu (Pic. 5).

Picture 6 – Food group menu, food group’s items list
After the food item has been selected (it’s marked by black background, see Picture 6), you need to
immerse the measuring probe into its flesh (or immerse it in water while measuring TDS) by two thirds of the
measuring probe’s length and press the button or . You’ll see the animated performance of the
measuring process on the screen (Picture 7).
Picture 7 – Measuring

After a few seconds the screen displays the nitrate concentration in the tested food item together with
the maximum allowable concentration in mg/kg; for water it displays salt content and the water use
recommendations (boil, put it through a filter, etc.) – see Picture 8.
Picture 8 – Results of measurement
Attention! After every measuring rub the measuring probe dry by a cotton napkin. Remains of
vegetables, fruits and water may negatively affect the measuring accuracy!
Attention! Avoid immersing the measuring probe’s connecting thread into the flesh of vegetables and
fruits or in water. It can lead to a short circuit and put the device out of operation! Optimal depth of
measuring probe’s immersion is 2/3 of its length.
