ISM Induction Oven Spot Survey - Example

Spot Survey routinely performed on an industrial induction drying oven.  Conducted to evaluate if staff were exposed to hazardous fields  at either occupational or non-occupational levels. The Top View shows all the spot survey points (in red).   The side view shows the various heights for each spot point.

24 Hour Monitoring

This innovative service provides continuous EMR monitoring of the environment for any duration. This enables the capture of short duration intermittent transmissions that may be missed when measurement periods are short, or to the measure the actual levels present over extended periods. Graphs can then be provided of field strength versus frequency against time.
