TM-192D is capable of measuring the electromagnetic field radiation intensity produced from:

• Electric transmission equipment
• Power lines
• Microwave ovens
• Air conditioners
• Refrigerators
• Computer monitors
• Video/audio devices

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 a quick, reliable and easy way to measure magnetic field radiation levels around power lines, home appliances and industrial devices.
• The tester is a cost-effective hand-held instrument that was designed and calibrated to measure magnetic field radiation at different bandwidths from 30Hz to 2000Hz.
• Display microTesla(uT) or milliGauss(mG) units.
• Data hold (HOLD), maximum Hold (MAX), and minimum Hold(MIN) function.
• Auto range or manual range select mode.
