ED78SPlus ELF/RF Dual mode EMF electrosmog meter


ED78SPlus Dual mode EMF meter

Use for:

This easy-to-use meter provides dual mode EMF detection; broadband power density measurements for common RF fields in the home, such as those produced by mobile phones, cordless DECT phones, wireless LANs (2.4GHz and 5GHz), bluetooth devices, wireless CCTV cameras (1.2GHz, 2.4GHz and 5GHz), microwave ovens - and milliGaussmeter measurements for ELF fields from overhead power lines, household wiring and appliances. This one meter will detect and measure almost all household EMFs!

Chronic exposure to EMFs (electromagnetic fields) has been linked by some studies to health issues such as childhood leukaemia, cancers, depression, disturbed sleep and electrical hypersensitivity.

EMFs commonly found in the home may be extra low frequency (ELF) fields from electrical appliances such as washing machines and hair dryers or from external sources such as overhead lines or underground cables. Alternatively, they may be radio frequency (RF) fields, produced by mobile and cordless phones, wireless networks and CCTV, microwave ovens and externally from mobile phone masts.

Two separate meters may be used for these two different types of EMFs, however this product combines both modes in one meter for little more than the price of an equivalent single meter! It is simple to use and pocket-sized. With this meter you can evaluate the risks in and around your home or office and take steps to reduce them.

Supplied new. Operating instructions are included. Requires one 9 volt alkaline battery (not included).

If you are unfamiliar with EMF meters, you might like to read the guide in our 'Help and Advice' section before reading the following information - or just ask us for advice; we prefer our customers to be happy with their purchase!
NOTE: The meters supplied by EMF UK are manufacturer calibrated and are suitable for general use. Customers who wish to use our meters for certain types of formal testing, for example occupational EMF assessment to meet the needs of the UK HSE or EU EMF Directives, will most likely need to arrange for certification of individual units at an approved calibration facility. This type of certification is a common requirement  for many types of test equipment, not just EMF meters.
