Might get this one when it comes out, was looking at getting the NFA1000 for measuring magnetic/electric fields, but its ~$2.3k which is a lot of money for basically the same function + sound
Bruce.this is great! You beat the NFA1000 with an extra digit of precision in the E-field, which was a surprise to me. I have a few questions --- * Does this have an audio component (aka, the 'geiger effect')? I am hoping to mount it on a pole sometimes as a super buzzstick. * What would be a text paragraph description of how to intepret the progress meter bar across the top -- is it a time delay slow moving average, is it logarhythmic, etc? * Given how temperamental potential-free E-field measurements are, how distant does one need to be while taking a measurement? For example, if I wanted to take 9 measurements in a grid pattern on a bed (a la 9PM NFA1000 measurement), how far should a person stand away and how long should we wait for settling before recording the measurement? I hope to raid my piggy bank for one before the summer is out. Bravo for a job well done.
Thank you! We focussed heavily on low end sensitivity. Yes, 'Geiger counter effect' like other meters. We're still finalizing and testing various meter bar motions. SLT will have documentation for 9 pt data collection.
I am so happy to see this meter :D!!!!!!!!!!!!!!!!!!!!!!!!!!! any chance we could talk off line about it? I do have questions and it seems hard to reach you
the magnetic field limit is 100 mG? That seems pretty low. I use the Alpha Labs which goes up to 2000. Instances that come to mind when it goes over 100 mG, is near a microwave oven, stick vacuums, blenders. Spinning hard drives (SSD?) in laptops?
Thanks for your feedback. We were asked to design a meter with true, excellent weak signal sensitivity for Building Biology standards... within a realistic price range. The 100 mG limit is on the individual X, Y and Z sensor axis, so the combined 3D display could be 170 mG. Our perspective on extremely high fields is they simply need to be avoided or fixed - whether they are 50 mG or 500 mG. And long-term daily, constant exposure to levels beyond the range of the EM3 is a problem in any case... unless the current Safety Standards are not a concern ;-) If you need to know precise levels at inches or cm distances, it's often more accurate to measure at a further distance and use math to calculate the near-field levels. Then also consider if someone would actually be that close to that appliance or device to actually receive that level of constant exposure.
@@9ci good answer. Agreed...anything more then a 4 mG for prolonged exposure - say while driving, I want to avoid. Almost always use external wired keyboards...not typing on a laptop keyboard. Driving - ideally less then 2 mG, but usually can't achieve that unless using G-Iron, which I travel with...for use while renting a car. Already "permanently" installed in daily drive. But good to know the limit could be 170 mG on this meter. This EM3 might be better for measuring in car foot wells - where it is darker. The Alpha Labs needs good ambient lighting or it can't be seen readily. I usually don't travel with a EF meter -- one too many...but nice to see this combo. If only there could have been a DE measurement too! ;) Then I could leave the Alpha Labs / Greenwave at home! Always some Cornets (MF-EF-RF)...but I hate the measurement units, among other negatives.
The RF meters would be more practical if you could hone in on a frequency with a display. There’s too much noise pollution in a a city like I live in LA.
Great gear as always Bruce, thanks! 💯
Message passed along - Thank you!

The NFA1000 theoretically has a wider frequency up to 1000kHz, but not many can afford a meter at that price.

Thank you! We are extremely busy for individual support. Please connect with Safe Living Technologies for questions.
@@9ci just got a degree in Electrical Engineering, I love the work of 9CI, any chance I could come aboard?

What can you do with the USB port? Can you log data? Can you connect it to a computer for continuous real-time monitoring? Thanks
Just external power for continuous operation.

NEUROSURGEON DR.Jack Kruse would tell you To move the hell away from that city, or risk serious problems
