The COM MonitorThe COM meter is designed specifically to measure mobile phone masts. The green lights represent the precautionary levels set in some European countries, the yellow and red lights represent radiation beyond that which has now been widely reported to be having adverse health effects on the general population. To hire: £25 per week (please telephone +44 (0)1353 778814 to arrange). HIRE this together with the COM monitor, and save £10.00 on the price of hiring them separately |
'COM' Microwave Monitor - Further Information
Technical specifications
|
The 'COM' microwave monitor measures microwave fields from mobile phone base stations (including TETRA and 3G - but see below), mobile phones, digital cordless (DECT) phones, 'wireless home' computer systems, radio-based baby alarms, microwave ovens, etc. The monitors come complete with full instructions. It is interesting (and often worrying) to see how far away you need to be from a microwave oven or mobile phone before it stops reading over-scale!
The COM scale covers the range of precautionary guidance that a number of European countries have adopted. The bottom green equals the old Salzburg maximum residential level (it has since been reduced further to 0.1 V/m), and the reds (4 to 6 V/m) equal the Italian and Swiss limits. ICNIRP guidance levels are from about 40 to 60 V/m and are far too high, in our and these countries' opinions, for residential exposure from mobile phone masts. Please note that because 3G/UMTS systems are "spread-spectrum", the apparent strength will be less than an equivalent GSM signal by a factor of somewhere between 5 and 20. This is because the power (watts/m2) is spread across a wide frequency band and so the signal level in V/m is that much lower. This means that although there may be emissions from the transmitting source, the COM meter may not pick some or all of them up, if the minimum meter threshold of 0.7 V/m is not reached.
Since the COM was designed, evidence is accumulating that pulsing microwave levels above 0.05 V/m are producing reports of adverse health effects. The A-COM and the Electrosmog Detector were designed to detect and make audible pulsing radiation below 0.7 V/m, the sensitivity threshold of the COM.
