TN2011 Electromagnetic Radiation Detector

TN2011 Electromagnetic Radiation Detector

1） Application
1. Used for environmental electromagnetic radiation testing: measuring radiation sources such as living rooms, offices, computer rooms, control rooms, cables, high-voltage lines, monitors, transmitters, etc.
2. Used for electromagnetic radiation measurement of household appliances: testing and analysis of radiation sources such as mobile phones, (grounded computers) computers, televisions, copiers, fax machines, air conditioners, refrigerators, etc.

This instrument is a new generation product for measuring electromagnetic radiation, and its biggest feature is its low price and accurate measurement values. This instrument has the following advantages compared to some instruments sold in the market at the same price for testing magnetic fields:

1. This instrument returns to zero when there is no radiation, while some instruments in the same price range on the market that test magnetic fields have a value of 0.02 μ T or 0.03 μ T when there is no radiation
2. Some testers of the same price in the market can only test low-frequency radiation and cannot test mobile phone radiation, but TN2011 precisely has the ability to accurately measure both low-frequency radiation and mobile phone radiation intensity
3. Buying instruments with more features at the same price,

2） Characteristics
1. Easy to operate and able to quickly measure the electromagnetic radiation intensity around household appliances, wires, and industrial equipment.
2. Value for money, easy to carry.
3. The test frequency band is wide and can be measured in two levels: high frequency and low frequency.
4. The minimum frequency for precise testing and measurement of electromagnetic radiation can reach 5Hz.
5. The design complies with CE standards.

4） Measurement program
1. Press the power switch and set the low-frequency Low or high-frequency High button according to the measurement needs.
2. The handheld instrument slowly approaches the object to be tested, knowing that the closer it comes into contact with the object, the greater the electromagnetic radiation value. Note: Remote measurement of high-pressure objects is sufficient.
3. Try changing the instrument angle during the measurement process to obtain the maximum measurement value.
4. If the power of the measured object is turned off during the measurement process, the instrument reading should return to zero state unless there are other interferences.

5） Regarding batteries
1. When the battery symbol is displayed in the upper right corner of the LCD, it indicates that the battery is low. Please replace the battery in a timely manner.
2. When the instrument is not in use for storage, the battery should be removed.
