NITRAGE TESTER and GEIGER COUNTER DOSIMETER Réf. DRNITRAT

Nitrate-tester is intended for an estimation (express analysis) of the quantitative maintenance of nitrates in vegetables, fruit, in fresh meat, and also in products applied, for a food of children. Checking the content and quantity of nitrates in an analyzed product is made by piercing of a measured product by a probe located in the bottom part of the device.

In the nitrate-tester "SOEKS" for each product the norm of maximum concentration limit (maximum permissible concentration) nitrates is set. Unlike out-of-date devices with the pointer indicator in which products were combined in groups, nitrate-tester "SOEKS" is adjusted on a concrete product. As a result of measurement you will see on the display the exact quantity of the maintenance of nitrates in milligrams on kg of a checked product, and also the recommendation about the validity to the use by indication of green, yellow or red color.

Nitrate-tester represents easily located in your hand device weighting only 150 grams. You have only to switch the device, to choose from the list a product and to receive result. Also the given device has the second function which will allow you to define radiation level in the atmosphere! The simplicity of use, convenience, reliability and reliability, all this is accessible now and is ready to serve you!

Principle of operation:
Geiger Counter detects beta particles and gamma rays and X, called ionizing radiation, with great sensitivity. It has Beta particles, and ionization created by X and Gamma radiation, indicating the 'amount of energy, transmitted to the material per unit time.
The unit displayed is the Micro Rem per hour (microRem / h) or micro Sievert per hour (microSv / h). It corresponds to an equivalent dose received by the human body for an hour, or 'dose rate'.
Reminders on the radio-activity: :
The matter is made of atoms. Each atom has a nucleus composed of protons and neutrons. The core is surrounded by electrons orbiting like satellites. Radioactive materials spontaneously emit radiation Gamma or X and / or beta particles or sometimes alpha.
Beta particles are electrons. Because of their charge, they react strongly with matter. They travel a few centimeters to several meters in the air. Aluminum foil can stop them.
Alpha particles are helium nuclei, or 2 protons and 2 neutrons. They travel a few centimeters in air, a sheet of paper can stop them.
Gamma rays are electromagnetic radiation formed during physical phenomena occurring within the nucleus of the atom. They are capable of producing ions directly or indirectly (atoms or molecules of non-zero electric charge) when they pass through matter. They can travel tens of meters of the air age. Their penetration may be very large, very thick lead and concrete and strongly attenuates.
X-rays Gamma rays are similar to but trained in physical phenomena occurring within the electron cloud of the atom. They are used in medicine and rarely found in nature.
