EMF Meter EMF Detector GQ EMF-390 Tri-Field Electromagnetic Radiation Detector 3-in-1 RF meter 5G Cell Tower Wifi 10G & Data Log 2.5G Spectrum Analyzer Radio Frequency Detector Ghost Hunting Equipment

looks fair enough. It is a US device that works better than I expected. The picture given does not do it justice.I Have been checking the EMF on various items and looking at the RF output from computers etc.The one thing I'm stumped over is the measure of EF. If I hold the unit in a certain way I end up measuring high levels. Is that me? I will have to get used to this item before I can give it a better review.I've already used the meter on one task where I needed to check for levels of EMF on a charging battery in a laptop to ascertain whether there could be high levels damaging the adjacent hard drive.

Works well. Successfully detects magnetic fields, electrostatic fields and RF.I have used it to easily locate electrosmog sources in an industrial, office and home environment. It revealed some surprises and allowed me to formulate a strategy based on more than guesswork and assumptions.However, as with all cheap consumer meters, the accuracy is unknown (calibrated accuracy costs a lot of money). So it's difficult to use as a gauge of long term low level exposure. But it will certainly allow you to test if your changes and protective measures are flawed.Well worth the money. A good buy.

Easy to pay nearly double for a device with smaller ranges. Good battery life. Leave backlight on as timer too short at 30". RFs less than I thought but EFs higher. Keep one metre away from appliances like fans and radios. Keep 50 cm away from power sockets, even when unused. My fusebox has constant high pulses of EF, even though everything is switched off -- keep well away. Biggest surprise was a 30 m cell-tower: only 5-10 mW/m2 (with pulses to 20+) a mere 30 m away! WHO safe limit is 100 mW/m2 but mid-band 5G already exceeds this in busy CBDs.

Hi bought this for the sake of the wife having had a pacemaker we were both told that she was to stay clear of the microwave what a shock the range of the emf from the microwave and when it was used on convection modeafter that i could not stop myself testing other household gadgetskev

Great little device with a great battery life.Best price on on the web.Used this on a smart meter in mums cupboard and was shocked it pitched at 298. EMF. will be getting this taken out as its dangerously high. Would never have known.Fits nicely in bag or pocket to take anywhere for curiosity testing..You will be shocked at your xmas lights and led bulbs. :(Best purchase for my piece of mind..

It does all I wanted- to set a safe environment to live around.

Please realise that this device doesn't measure 5G in the higher bands. 5G frequency goes much higher than the 10GHz this device is limited to. For 5G we need devices that can measure to 60GHz.The seller should remove the 5G as it is false advertising.

This equipment is very very great quality & value for the price,It has high quality reader for the price,high quality case holder and charging usb cable etc,It only takes about 3o mins to an hour to read the very quick instruction manual and be fluent in operating it naturally,It's much better quality than my more expensive reader.I highly recommend this,It's perfect for commercial home safety readings etc!It's a wise purchase I believe most people will be very happy with✓
