Hi Ben.
Electric fields generated around household appliances are normally very
weak. An exception is a CRT based TV that has such a strong field
around it that you can easily get shocks by just tuching the screen.
There are tools that do mesure the electric field around a charged object.
They are called: Electrometer or Electric field meter.
Most electrometers are based on a component called FET (Field effect
transistor).
Here is a small charge detector project for you with plenty of information
about
how it works:

There are also a lots of other interesting articles to read about
electricity here:
