เครื่องวัดความเร็วลม รุ่น TM-191 แบรนด์ TENMARS
EMF Meter
The Tenmars TM-191 EMF / ELF Meter is and easy to use digital EMF meter that measures the level of EMF magnetic field radiation from power lines, computers, kitchen appliances, and more! The Tenmars TM-191 test meter could not be easier to use, just turn it on and get accurate reliable readings. Perfect for situations needing high resolution measurements. Switchable between either microTesla or milliGauss at the press of a button and can display and hold maximum readings.
This meter is very sensitive and has a very wide measurement range up to 2000mG and has a clear and easy to read display.
Some interesting facts about Electromagnetic Fields (EMF) & ELF:
► An electromagnetic wave means the wave motion of the electromagnetic field (EMF).
► The TM191 is designed to measure electromagnetic fields of extremely low frequency (ELF) of 30 to 300Hz.
► It is capable of measuring the electromagnetic field radiation intensity that is produced from electric transmission equipment, power line, microwave oven, air conditioner, refrigerator, computer monitor, video/audio device and so forth.
► The magnetic field unit is Tesla (T), Gauss (G), mini-Gauss (mG) or micro-Tesla (μT).
► 1 T＝10,000 G
► 1μT＝10 mG
► 1 G＝1,000 mG
