The gaussmeter (magnetometer) is a high performing device for measuring electromagnetic waves generated by electromagnetic fields which are usually created in installations and operating instruments. The gaussmeter for electro magnetic fields, solar radiation and lux becomes more important each day due to the increased negative effects of the environment. The gaussmeter is for both personal and professional use for measuring such things as transformers, power lines and electrical devices. Electromagnetic fields may have an important influence on human beings (for instance, feeling unwell, nervous or even internal burns), independent of their frequency. The gaussmeter is also used extensively in the industrial sector and in research and development. The gaussmeter can be DIN ISO 9000 calibrated and certified and have other optional accessories available.
