It’s the professional features that differentiate the ME3851A from the ME3840B

Very important: It is more sensitive by a factor of 10 (smallest display resolution: 0.1 nT / 0.1 V/m). In conjunction with the frequency filter, even the lowest levels of DIRTY POWER can be detected.
NiMH rechargeable battery incl. battery charger / AC adaptor.
AC and DC outputs permit further analysis.
Increased reliability through offset control switch.
Perfectly suitable also for potential-free measurements with the help of the potential-free mounting for LF measurement devices.

Along with the filter module the instrument also includes all common advantages of the product line

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.
