Are you aware of the electromagnetic radiations, cause by Electro Magnetic Fields EMF, you are exposed during the day?

Those EMF fields, can be caused by some of the everyday appliances we use, or are surrounded of.

The Mustool® MT525 is one instrument with two funktions. It can test the electric field and the magnetic field radiation at the same time.  

I foud this tool very useful to check if our environment, where we live or spend a lot of time, is safe for us (in terms of electromagnetic radiation) or not.

For example, one place where we spend a lot of time is our bed. Do you know how much electromagnetic radiation your sleeping area is exposed to?


Although there is no scientific proof of EMF causing diseases, according a study of the World Health Organisation, the recommendation of the WHO are:

WHO's guidance

For high-level short-term exposures to EMF, adverse health effects have been scientifically established (ICNIRP, 2003). International exposure guidelines designed to protect workers and the public from these effects should be adopted by policy makers. EMF protection programs should include exposure measurements from sources where exposures might be expected to exceed limit values.



Mustool® MT525 Electromagnetic Radiaton Tester

  • General Description:

    This EMF detector, can detect electric field radiation and magnetic field emissions.

    Sound-light alarm, when the test result exceeds the safe value, the instrument will alarm automatically.

    Data locking, one-key lock of the radiation value.

    Equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital display.
    Radiation assessment, remind you whether the radiation value is safe or not.  Auto power-off.  
    Fashionable design, easy one-hand operation, easy to carry.


    Generally used for:

    Electromagnetic radiation monitoring: Monitor and learn about the existing electromagnetic radiation situation, indoor like household and apartment, office, outdoor and industrial site.
    Electromagnetic radiation test: Mobile phone, computer, TV set, refrigerator and high voltage cable radiation test. 
    Radiation protection product test: Test effects of radition-proof clothes, radiation-proof film and other prevention articles.
