Digital TRAIXIAL ELF Magnetic Field Meter
MODEL - KM 192
High Electromagnetic waves are generated by electric appliances, used in medical
institutions, Schools, Residences where people usually stay for a long time.
Precautions should be taken to prevent patients, Babies & other citizens from exposure
to high electromagnetic waves. An electromagnetic wave means the wave motion of electromagnetic field. It is a form of energy similar to light & heat that can be transmitted by radiation in the air or by an electric conductor.
FEATURES :• Uses three internal orthogonal sensors to test a wide range of ELF magnetic fields, independent of measurement angle• The tester is designed to provide the user a quick, reliable & easy way to measure magnetic field radiation levels around power lines, home appliances & industrial devices• The tester is a cost-effective hand-held instrument that is designed and calibrated to measure magnetic field radiation at different bandwidths from 30Hz to 2000Hz• Display micro tesla (mT) or milli Gauss (mG) units• Data hold (HOLD), Maximum Hold (MAX) and minimum Hold (MIN) function• Auto range or manual range select mode• Time and calendar function• Low battery indication• Over load display “OL”• Auto power off function
APPLICATIONS :• This meter is applied to measuring electromagnetic fields of extremely low frequency (ELF) of 30 to 2000Hz.• It is capable of measuring the electromagnetic fiel 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), milli-Gauss (mG) or micro-Tesla (mT).• 1T = 10,000 G• 1 G = 1,000 mG• 1 mT = 10mG
