LZT-1160 electromagnetic radiation tester is a new type of multifunctional electromagnetic radiation measuring instrument, to realize the high frequency radiation low-frequency radiation one and relatively accurate test. High frequency for testing and mobile phone, mobile phone electromagnetic understanding signal tower, wireless devices such as radiation; radiation frequency test field, used to test and understand the home appliances, computer, cable, high-voltage wire, transformer substation electricity, electric, power supply equipment of electromagnetic radiation
Shoot. According to the test results of the electromagnetic radiation treatment or effectively avoid, let users on the side of the electromagnetic radiation to fully understand.
Characteristics of two, instrument technology
simple operation, convenient test.
value, easy to carry.
targeted, high frequency / low frequency test.
perfect function, numerical locking, peak locking.
design is exquisite, beautiful professional.
design with CE.
Three, the application range of the apparatus
1 high frequency electromagnetic radiation test application: wireless router, mobile phone, mobile phone signal towers, TV signal tower, broadcast signal tower in the technical index of the instrument to test all sources of electromagnetic radiation.
2 low frequency electromagnetic radiation test application: computer, printer, fax machine, TV, air conditioner, refrigerator, washing machine, wire, audio, power supply, etc. the technical index of the instrument testing within the electricity, electricity, electricity and all other sources of electromagnetic radiation.
Four, technical indicators:

Five, measurement procedures and methods
1, press the power switch, set the low/high button on the right side of the screen display, such as μ W/cm2 radiation measurement model for high frequency, such as the right side of the screen display μ T radiation measurement model for low frequency, testing the use of high frequency or low frequency can be according to "three, the application range of the apparatus" selection.
Note: because the environment there may be interference of electromagnetic field, in the boot instrument may have small reading, not instrument failure.
2, a hand-held instrument slowly close to the source of electromagnetic radiation to be measured, such as the actual value of radiation in the technical index of the instrument testing in the instrument will have numerical display; such as instrument without reading the source of electromagnetic radiation is less than the minimum numerical machine reading of 1 μ W/cm2 or 0.01 μ T
Note: for high-pressure facility distance measurement can be, remember safety first.
Press the Data Hold button 3, measurement, the top of the screen displays "H" when the instrument is in numerical locking state, then press the unlock.
Press the Max Hold button 4, measurement, the top of the screen displays "Max" when the instrument is in peak locking state, then press the unlock. The maximum radiation this function is used to detect specific environment a time value.
4, when the instrument is the upper left corner of the show "that" when battery power is insufficient, please replace the battery.
Six, electromagnetic radiation hazards and suggestions
1, according to authoritative sources say: long-term exposure to electromagnetic fields, can lead to children suffering from leukemia; can cause cancer; reproductive effects; causes of spontaneous abortion of pregnant women and fetus malformation; lead to children's mental disabilities; also in the human visual system damage.
2, the above has not been fully confirmed, but most people still think should avoid long time exposure to electromagnetic fields. The United States Environmental Protection Agency called escape-cautious.
Status of electromagnetic radiation, recommend 3 regular monitoring of life and the workplace, and according to the measured results to rational distribution, so as to avoid long time exposure affects health in the electromagnetic field.
