Review: Accurate and simple to use 3 in 1 (EMF/EF/RF) meter - This meter is half the price of equivalent competitors and provides everything a budding home worker or concerned parent could possibly need. Easy to use and sensitive enough to be able to easily sense check that the meter readings are reliable (which they are with mine). Super accurate in fact, especially when held correctly (as shown in small printed instructions). I wanted it to check my home office and particularly the electric / electromagnetic field fields and radio frequencies (aka WiFi exposure) at my desk & kitchen table (for home working under lock down). With some small changes was able to reduce our exposure to all forms of invisible radiation by more than 10 times. Also was able to see change in RF in real time as I used WiFi on my iPad. I already knew that you should not hold your iPad in your hands and use WiFi but the results were an eye opener. Needless to say my desktop computer is not connected by Ethernet cable and favoured (whenever possible) over the iPad. I have also move the modem (which is really harmful at short range, shit these things should come with a serious health warning!) as far from me as possible. This device is a God send and only after I had bought this meter did I watch 'Better Call Saul'. So glad I went for this meter and would recommend to anyone remotely concerned about their health with all the debate raging over 5G
Review: EF not accurate due to response to our body - Excellent device BUT for some reason the EF reading jumps up to very high readings the moment I'm near it, touch it or hold it!!? I've read the instructions, hold it at the bottom where it's supposed to be held and keep it away from my body whilst holding it, but still it jumps up. How can I get an accurate RF reading if this keeps happening!?? I'm not sure whether to send back or does it need to be calibrated!? That being said its a great little detector with lots of great features.

## Questions & Answers

**Q: Does it detect ultrasonic sound frequencies? Like the mosquito alarm?**
A: No, only EMF / RF, electro magnetic spectrum not sound waves

**Q: Will this equipment detect electricity pylons for say up to 1 mile ? (i want to know before I purchase a new house)**
A: It really depends on the strength of the electromagnetic field being generated. An electromagnetic field decreases exponentially over distance, as a result I would suggest that a pylon carrying 400KV a mile away would be undetectable over the earths natural magnet field. This device is capable of detecting emissions from TV's, computers and other electrical systems within the home. So in short the answer is no.  If the pylon your concerned about is about a mile away I'm sure it would have no detrimental affect whatsoever.

**Q: Can this device function as a Geiger counter in the event of a nuclear incident please?**
A: No, definitely not. It measures electromagnetic radiation up to 10GHz, not nuclear radiation. It is mainly useful for detecting dangerous levels of non-ionising radiation from mobile phones, smart devices in general and. Microwave cookers etc. They do a Geiger counter version that does detect nuclear radiation. It detects beta and gamma radiation that would be emitted by a nuclear explosion but not alpha particles resulting from breathing in radioactive dust. However, beta and gamma radiation detection is generally the best indication of a nuclear event.

**Q: What is the maximum time period of data that can be recorded on onboard flash memory and transfered to PC?**
A: It is about 24Hrs for every seconds data.

### ⭐⭐⭐⭐⭐ very useful
*by N***K on 5 October 2021*

This was bought for several purposes , including an educational one. 3 modes and several settings are presented with differing information being able to be displayed. The accuracy of measurement is always a difficult one to prove without spending loads of money on certified kit but comparison to friends much more expensive hardware and my own spectrum analysers show similar results. The unit presents information on the radiating source (wifi, cell tower etc) which has proven to be useful and you can focus on certain bands of the spectrum as well as the automated scans. navigating the menus is not that intuitive so I would recommend spending some time with the manual and online research . In the basic mode it is great for use in comparative measures , the display is grey and black, not high deff but good enough and battery life is extremely good . manufacture support is accessible and helpful. a nice case, wrist strap and credit card references outlining good and bad levels of exposure is also useful. You can customise the alarms and led warning as well as some of the settings but you do not get on screen help so need to read the manual
