EMF Meter Digital True-RMS 3-Axis Gauss meter (DSP523) 60Hz Filter

Model #: DSP523

The DSP-523 uses a powerful digital signal processor that sets a new standard for AC gaussmeters.  Now you can ignore powerlines, bandpass powerlines and analyze powerline harmonics, all with one simple meter.

The first line shows you the total, unfiltered field strength.  The second line shows the field strength with one of four digital filters selected:

  • Ignore 60Hz + Harmonics
  • Ignore 60Hz Only
  • Bandpass 60Hz + Harmonics
  • Bandpass 60Hz Only

Selectable axis, graphing, max hold, and a variable backlight are just icing on the cake.

No other gaussmeter has the ability to accurately notch or bandpass powerline fields and harmonics while still passing other frequencies.  Easy to use, and innovative

50 Hz European Fields: Need to use the meter in Europe where power line are 50Hz instead of 60Hz?  No problem, you can switch between 50Hz and 60Hz filtering in the menu.

What our customers say...

I had a chance to use the DSP-523 yesterday on location concurrently with two KII and one Cell Sensor EMF Meters. We also had 3 single axis arrays placed in the area. Throughout the evening we received several 2-3mg spikes on one of the KII's, one spike on the second KII and one 3mG hit on an array. We were in a location with no man-made immediate power surces or exterior lighting as it was outdoors with power lines approximately 50 yards away from our central area. Throughout the evening we were also able to clearly see a pattern of stable EMF in the local area measuring .03 - .50 mg on the DSP-523 as well as see the powerline contamination which routinely stayed constant at .10 to frequent 3.90x spikes. Being able to isolate and watch the power line EMF in the field was immediate confirmation of the false positive occasional spikes on the KIIs. The LED was incredibly easy to read throughout the evening as well. There was only one inconsistent reading received the entire evening, which was recorded on the DSP-523 of 4.92 and never replicated and was outside the normal recorded range for the power lines. In my opinion, compared to the DSP-523, the KII meters had no value in the field next to the DSP-523's accuracy and ability to filter power line noise! Even in 33 degree weather, the meter was stable, easy to read with no temperature related issues as well! While 2 of 3 arrays failed prematurely due to battery loss directly related to conditions.

The DSP-523 has really set a new standard for EMF meters. It is full-featured, sensitive, easy to operate and overall a sturdy and high-quality device. In my opinion, the ability to filter 50/60Hz contamination makes the DSP-523 the only truly useful device for investigation and research. The controls and interface were also very well designed. When I first read the documentation I must admit I was a bit intimidated by the myriad of features available on the DSP-523. However, after using the device for a few minutes I had no trouble understanding the interface and navigating the menus. That sort of usability for a full-featured device is not trivial to design.
