EMFields PRO meterThe PRO measures Electromagnetic Fields (EMFs) produced near powerlines, substations or transformers, house wiring & electrical appliances. The PRO meter will be able to help you check if you and your family are too highly exposed, at home, at school and at work. The PRO meter will be able to help you measure the EMF levels in your environment. It measures up to 20 microtesla and 2000 volts per metre. The UK average residential magnetic field is about 0.05 microtesla. Ideally electric fields should be 10 volts per metre or less. To hire: £35 per week (please telephone +44 (0)1353 778814 to arrange) |

Technical specifications

The EMFields PRO has a digital readout and measures electric and magnetic fields with frequencies from 7 to 2000 Hz (±3 dB). The magnetic scale has a resolution of 0.01 microtesla (10 nanotesla) and a full scale of 19.99 microtesla. The electric scale has a resolution of 1 volt/metre and a full scale of 1999 V/m (with accuracy of ±2% ±3 digits at 50/60 Hz).
This is the meter to use for EMFs from electric power sources - overhead lines, substations, underground cables, house wiring, electrical appliances and equipment, etc. You can use it to measure the EMF fields at home and in the workplace. It is hand-held (see photo) and with it you can measure the fields at any time of the day or night. The hire meters are sent out with full instructions by Royal Mail 1st class recorded delivery.
At work you may be exposed to quite high levels of fields. In the office environment, there are computers, VDUs, cabling, faxes, photocopiers, printers, fans, table lamps, scanners and fluorescent lighting. Fluorescent lighting can generate very high levels of electromagnetic fields, and have been found to be responsible for occupational ill-health, frequent work absence, and for initiating electrical sensitivity, a seriously debilitating illness.
Power consumption, and the associated electromagnetic field levels, varies over time in a house. The peak periods of power demand on the circuit are likely to be between 8.00 a.m. and 9.30 a.m. and between 4.30 p.m. and 6.30 p.m. depending on the area where you live. There may be a period of high demand between 12 midnight - 8.00 a.m. if there are many people in your neighbourhood who use night storage heaters. In cold weather, field levels can be up to three times higher than in periods of warmer weather, because of the greater use of electric heating and cooking. If your power supply circuit serves shops, schools, or industry, especially if these include long days or opening times, or overnight working, it may significantly change power demand and field levels both inside and outside the house.
The fields in your garden may vary due to the presence of overhead or underground cables, substations or transformers.
