Electromagnetic Radiation Meter Tester for mobile phone radiation shield anti radiation sticker SFC
Cell phone radiation tester is a novel design, compact appearance, stable performance, low cost mobile phone radiation post-test instruments. Our this new model’ s probe is designed like antenna, this design makes the probe better point to and more accurate and convenient to detect radiation sources. The front and back of the probe is different sensitivity, use the positive front of probe to detect the low radiation cell phone positive ; use the back of probe to detect the stronger mobile phone radiation.

Tester Theory
The tester can detect 800-2000MHz band electromagnetic signals in a special probe. When the probe detect the electromagnetic waves within this frequency band signal, the electromagnetic field strength of signal voltage will be displayed on LCD, the display unit mv/ cm2. Maximum display value is 1999. It will appear 1 if this value over 1999.
This tester can demo a simple experiments for GSM mobile phone radiation. It is suited for effect demo of mobile phone radiation ( comparison test) . Of course, when doing comparative experiments, please kindly note: the test result is different per many factors, such as phone models, GSM network, testing environment etc.. At the same time, we have to understand that this instrument is not a professional measuring instruments, can only be used for simple observation of mobile phone radiation changing ( electromagnetic field strength) .
How to USE?
* New tester is without battery, at first open the case and put into 1pcs 9V battery. When screen show battery sign, it awake you to change new battery.
* Press power button, you can start to use it if the screen shows 000. Press power button again, it power off. The display value maybe fluctuate + / -000 in different conditions, this is normal and it won’ t affect the test demo.
* Using another photo to call the tested photo/ or call another phones with the tested phone ( don’ t pick up) , and use the tester to find the antenna radiation sources ( top/ bottom/ left/ right of phone backside) with probe. When the display value is max, then it is the antenna radiation sources. Test several times and write down the average value, this is used as original value of mobile phone radiation before sticking our product.
Note: some mobile phone’ s antenna is on both top and bottom; and some mobile phone ( specially Chinese mobile phone) is set on keyboard.
* Get off the paper of sticker and stick to the place of antenna radiation sources, then use another photo to call the tested photo/ or call another phones with the tested phone ( don’ t pick up) , you will find the display value lower down much.
- The display value is different even in the same environment, while use different probe tests ( front or back) , signal strength of emission or reception of different brands of mobile phone. And the distance between the probe and the phone will also directly affect the test data.
- Different antenna location for different brands of mobile phone, please use the equipment carefully to find the probe. The higher display values are, the nearest mobile antenna is. Then paste the radiation patch to compare test.
- This test is only observed on radiation shielding effectiveness, another function of our stickers can resolve radiation wave targets the human brain can not be observed.
-In order to offer better demo, it must to stick on the place of antenna radiation sources to demo Shielding Effectiveness. However, in actual use, because some mobile phone antenna is mounted on the camera around, can not be affixed directly. Then just simply paste the patch on the phone back . If what you ordered is dual function of patch, both anti radiation and battery saver/ extender, you can also stick on batteries. If you don’ t stick where the antenna is, the demo of shielding effectiveness maybe be poorly observed.
For how to demo, you can reference to our old tester.

-This tester only for GSM phones. If for CDMA mobile phone, you need put the phone’ s antenna and tester area very close and see carefully just callings in/ out, the display value is very low and disappear soon. This prove radiation is less for CDMA phones.
