In this video Guy Hudson talks about the Acousticom 2 High Frequency Meter.
This meter is a core part of equipment for anyone interested in Electrosensitivity and low electrosmog environments. It allows people to investigate the levels and sources of electrosmog in the most simple way and direct way. For what it does it is very good value for money. Not the quite cheapest meter on the market but the best for the money.
Technical Description from the Manufacturer
The Acousticom 2 is our newest microwave detector. It presents RF measurements as an audio signal, with LEDs and an alarm at high levels of RF (you can also switch the sound off if you prefer to be less obvious when taking readings). With simple controls, easy to read results, but still using the same advanced microwave detector as our Acoustimeter, this instrument is perfect for those on a budget. It is smaller and lighter than the Acoustimeter, and comes in its own carry pouch.
The Acousticom 2 was designed using the experience gained from many years of practical RF and microwave measurements. The advanced RF detector is the same as that used in the Acoustimeter. LED lights display the peak levels of microwave electromagnetic fields from 200 MHz up to over 8000 MHz (8 GHz), covering the frequencies used by most modern communication systems encountered in our everyday environment. This includes TETRA, all mobile phone systems including 4G/LTE, Smart Meters, and all WiFi and WiMax frequencies. The LEDs update rapidly, and allow you to quickly gauge the levels in an area and find any hot-spots. Its readout is sensitive to 0.01 V/m. When two LEDs are both lit next to each other, the exposure level is halfway between the two. This is only for levels above 0.1 V/m, e.g. when both 0.10 and 0.30 V/m are lit, the level is about 0.20 V/m (halfway between).
