The meter FME is an economic tool and hand-held and intended calibrated to measure electromagnetic field radiation at different bandwidths. An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics. The two largest categories are the single axis and the tri-axis. Single-axis meters are cheaper than tri-axis meters but take longer to complete a survey because the meter only measures one dimension of the field. Single-axis instruments have to be tilted and turned on all three axes to obtain a full measurement. A tri-axis meter measures all three axes simultaneously, but these models tend to be more expensive. Electromagnetic fields can be generated by AC or DC currents. An EMF meter can measure AC electromagnetic fields, which are usually emitted from man-made sources such as electrical wiring, while gaussmeter or magnetometers measure DC fields, which occur naturally in Earth's geomagnetic field and are emitted from other sources where direct current is present. Features: Display: Semi-liquid crystal display (three digit) Max. Indication: 1999 Range: 50Hz~2000MHz Sampling Time: about 0.4s Working Voltage: 9V Dimensions: 13.2 x 6.9 x 2.9 cm Battery Model: 6F22 9V Weight: 105 g Product application: 1. Used for environmental electromagnetic radiation testing: measurement of radiation sources such as living rooms, offices, computer rooms, control rooms, cables, high-voltage lines, and monitors. 2. Used for electromagnetic radiation measurement of household appliances: mobile phone, computer, computer, copier, fax machine, air conditioner, refrigerator, and other radiation sources test analysis. Product features: 1. A simple operation can quickly measure the electromagnetic radiation intensity around home appliances, wires, and industrial equipment. 2. Wide test frequency band. 3. The numerical contrast is obvious, suitable for the measurement demonstration of the effects of radiation products, and personal understanding of radiation. 4. The design conforms to CE. 5. Excellent value for money and easy to carry. 6. The performance of this instrument for measuring mobile phones is very stable. It will not appear that some instruments on the market have values ​​at the beginning and then slowly return to zero when testing mobile phones. 7. Enjoy different measurement quality at the same price, friends no longer have to worry about not finding a reliable electromagnetic radiation tester. Measurement procedure: 1. Press the power switch, aim at the electrical appliance to be measured and prepare to measure 2. The handheld instrument slowly approaches the object to be measured until it comes into contact with it. Note: High-pressure objects can be measured from a distance. 3. Try to change the angle of the instrument during the measurement process to achieve the best measurement effect. 4. If the power of the object is turned off during the measurement process, the instrument reading should return to the zero states unless there is other interference. Regarding the battery: 1. When the test data of the instrument becomes small or does not alarm, it means that the power is insufficient, please replace the battery in time. 2. Remove the battery when the instrument is not in need of storage.
