Main difference to the ME3851A:

• The frequency response is extended to the full 400 kHz, as specified in the TCO directive.
• This is an important decision criterion, if you offer professional LF measurements, because ...
• modern switching power supplies move into ever higher frequency ranges and
• many induction cookers work between 100 and 200 kHz.
• Last but not least, the TCO policy is a well-known and recognized seal, giving the consumer some security.

Apart from the filter module, the ME3951A also fulfills all the other advantages of the series

• The filter module for quantitative differentiation the artificial harmonics ("dirty power") as well as traction and mains power supply is included like in the ME3840B.
• The filter module is indispensable for applying the much stricter guidelines recommended by the standard of building biology, especially for the frequency range from 2 kHz (“dirty power”) .
• LCD reads comfortably in big numbers and directly in the units of the SBM standard values without further calculations.
• The "Geiger counter effect" makes it easier to find hidden sources.
• The included detailed measurement instruction enables the user to perform relevant measurements of EMF – even without technical expertise. With the help of this instrument you can spot - even obscured - sources of LF pollution.
• Also the manual includes the recommendations for limiting values according to the standard of building biology SBM, which allow for a meaningful assessment of the personal level of EMF pollution.
• Many patents have been granted to us, the devices have tenthousandfold proven their reliability, and have shown to be leading-edge in their price categories.
