Feature:1. Capacitive Screen with 3-Color Display: You can select the interface of fruits, vegetables, meat, fish, water quality, and radiation detection in the main menu, or click the setting button in the upper left corner to open the setting menu. Three-color display, clear results, distinguish the safety of fruits and vegetables, to avoids excessive intake of nitrates and other harmful substances, and keep away from radiation.2. Multi-functional Design: It is a test instrument that can quickly detect the nitrate content in fruits, vegetables and meat, as well as the solid content in water. At the same time, this instrument can also detect the background radiation dose, as well as the radiation dose in objects, foodstuffs, building materials, and other products containing radioactive elements.3. Nitrate Detection: The tester technology assists in the quick detection of various salt ions such as chloride ions, sulfate ions, nitrate ions, and nitrite ion concentrations. The instrument has been calibrated to accurately display the concentration of nitrate ions.4. Total Dissolved Solids Detection: It can detect the content of salts dissolved in water. The machine works on the principle of total dissolved solids detection. It is mainly measures the actual resistance to detect the content of salts and acids dissolved in water, to help you confirm the quality of the water used daily.5. Background Radiation and Object Radiation Dose Detection: The main measurement is the magnitude of the ionizing radiation dose (gamma rays and beta rays) and nuclear radiation. It supports the selection of the units of radiation measurement. It is also possible to change the volumes of the instrument.6. BT and APP Control: You can turn on BT to connect the device to a smartphone and perform measurements using that application. (Note: After the device is connected to the smartphone app, it can only be controlled by your smartphone.)7. Auto Power Off: Includes an auto power-off function and supports auto power-off time settings of 1, 3, 5, 10, 15, 20, and 30 minutes. The unit can enter sleep mode or resume working mode by pressing the power switch once. If the instrument has not been used for more than 40 seconds, it will automatically enter sleep mode after that time.8. Multiple Languages System: Multi-language design, you can switch between English, Chinese, Russian, Ukrainian, and Arabic according to your usage habits.Specification:Using the nitrate, water and radiation testing technology, detects nitrate levels in 64 of the most commonly consumed fruit and vegetables and all types of meat and fish. Additionally, it can detect total dissolved solids in water or water hardness, as well as background radiation in your immediate environment alerting you to unsafe radiation exposure. Capacitive screen with 3-color display, clear results, distinguish the safety of fruits and vegetables, to avoids excessive intake of nitrates and other harmful substances, and keep away from radiation.
