ED-85EXPlus EMF RF meter


ED-85EX+ (1MHz-8GHz) RF Electrosmog Meter - External SMA Connector, Frequency Display, Dual Mode & Data Logging

Use for:

This meter is suitable for the measurement of common RF fields in the home and office, such as those produced by mobile phones, cordless DECT phones, wireless LANs, bluetooth devices, wireless CCTV cameras and microwave ovens. The ED85EXS+ meter has an exceptionally wide frequency range, which includes Tetra and the latest 5GHz wireless-N networks, and additionally has a sound signature function to help identify the specific source of those EMFs.

The ED85EXS+ has a 50 ohm SMA connector to allow connection of an external whip antenna, telescopic antenna, log-periodic antenna or other compatible source of RF. Please note that the free included whip antenna is most suitable for wifi and mobile phones and will be less effective in other areas of this meter's frequency range. If in you are in any doubt about your intended application, please enquire before you purchase. (Alternative antennae are available in our accessories section).

Note: for general home use the ED78S dual mode or ED88TPlus tri-mode meter may be more suitable - please see our 'combined meters'.

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