The ELF PF4 Power-frequency Meter
(Made in UK)
The ELF PF4 meter is the updated version of the EMFields PRO meter, and measures Electromagnetic Fields (EMFs) produced near powerlines, substations or transformers, house wiring and electrical appliances.
It will be able to help you check if you and your family are exposed to levels of EMF that are too high, at home, at school and at work.
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.
The EMFields ELF has a digital readout and measures electric and magnetic fields with frequencies from 10 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 electromagnetic fields (EMFs) at home and in the workplace. It is hand-held 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. If you need to take readings urgently, perhaps there is little time before a decision about buying a property needs to be made, you can request our priority post service which means the meter is sent Special Delivery. If you place the order before 11.00 a.m, it will usually be sent the same day, and you should receive it the following day. Both Recorded and Special Deliveries are signed-for services. We can send the meter to your work address if this is more convenient for you.
