Product information "LF Analyser ME3851A"

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.
