DP-1000 Electromagnetic Radiation Tester, Electromagnetic Field Intensity Tester is a new generation of instrument for testing electromagnetic radiation. It successfully tests the electric field radiation and magnetic field radiation and achieves the best test results. It is used for personal testing and understanding of indoors (home appliances, computers). The current status of electromagnetic radiation in the environment (substation, high-voltage line, transformer, machine room, cell phone signal tower, etc.) in outdoor (substation, mobile phone, wireless equipment, etc.). According to the test results, the electromagnetic radiation can be reasonably treated or effectively evaded, helping individuals and families to stay away from radiation and enter health.
Technical features:
â—‡ Easy to operate and easy to test.
The food is great value for money and is easy to carry.
â—‡ Test band width, high, medium and low full frequency test.
â—‡ Powerful, electric field, magnetic field radiation compatibility test.
â—‡ Beautifully designed and professional in appearance.
â—‡ Design conforms to CE.
Application range:
1. Outdoor environment electromagnetic radiation test application: substation, high voltage
Line, transformer, power distribution room, cable, cell phone signal tower, electricity
Vision signal tower, broadcast signal tower, etc.
All sources of electromagnetic radiation inside.
2. Indoor environment electromagnetic radiation test application: computer, television,
Copier, fax machine, air conditioner, refrigerator, stereo, laundry
Machine, wire, power supply, mobile phone, wireless router, etc.
Test all sources of electromagnetic radiation within the specifications.

Measurement procedures and methods:
1. Press the power switch and set the E/H button. If V/m is displayed on the right side of the screen, it is the electric field radiation test mode, as shown on the right side of the screen.
μT is the magnetic field radiation test mode, and the (electric field/magnetic field) mode can be switched at any time according to the test requirements.
※Note: Due to electromagnetic interference in the environment, the instrument may have a small reading when it is turned on, not the instrument is faulty.
2. The handheld instrument slowly approaches the electromagnetic radiation source to be tested. If the actual radiation value is within the instrument test specification, the instrument will have a numerical value.
If the instrument has no reading, the electromagnetic radiation value of the radiation source is less than the machine's minimum reading of 1V/m or 0.01μT.
※Note: For high-speed facilities, long-distance measurement can be considered, and it is important to pay attention to safety.
3. Press and hold the Data Hold button during the measurement process. The instrument reading will be locked. If you do not need to lock, release the button.
4. When the digital display is unclear or the number is flashing and cannot be reset to zero, it indicates that the battery is low. Please replace the battery in time.
Electromagnetic radiation hazards and recommendations:
1. According to authoritative sources: long-term exposure to electromagnetic fields may cause children to develop leukemia; can induce cancer; affect reproduction;
Pregnant women with spontaneous abortion and fetal malformations; causing children to be mentally disabled; also harmful to the human visual system.
2. Although the above description has not been fully confirmed, most people still believe that long-term exposure to electromagnetic fields should be avoided. The US Environmental Protection Agency said
It is - cautious avoidance.
3. It is recommended that you regularly monitor the electromagnetic radiation status of your living and office space, and re-arrange the layout according to the measured results to avoid affecting health due to prolonged exposure to electromagnetic fields.
Relevant information and reference standards:
Recommended according to relevant reports:
The environmental radiation tolerance of the professional personnel for 8 hours of continuous exposure per day is 14V/m or 100μT.
The electromagnetic radiation value of the public environment is not more than 10V/m or 0.4μT.
Note: The above two sets of data are for user's reference only and do not have legal effect.
