An electrostatic measurement is particularly important to check whether surfaces, components or the human body are electrostatically charged. If a discharge occurs, electronic components can be damaged. In the worst case, flames can form with flammable gases and liquids. Such electrostatic charges can be found with the environmental tester. The electromagnetic field meter is therefore used for checking in ESD-protected production workshops. The measuring range of the electromagnetic field meter is ±60 kV DC.

The environmental tester can be grounded with the alligator clip included in the scope of delivery so that the electromagnetic field meter does not lose its measurement result itself or, if necessary, damage components in a production workshop due to an electric shock. The lasers on the electromagnetic field meter are used to optimally align the sensors.

In addition to measuring radiation, the environmental tester can measure ambient temperature and humidity at the same time. For mobile use, the electromagnetic field meter is operated with a 9 V block battery. The operating time for the electromagnetic field meter is a maximum of 20 hours. The current battery charge is displayed by the electromagnetic field meter via the battery status indicator.
