I have never seen a thing like that,

seriously? you've never seen a handheld light meter??

but perhaps it is something with
which you measure the light intensity. Is this correct?

it is.

The other question is, why would you need such a device, when every
digital camera nowadays will readily tell you if the image is over- or
underexposed and will show a nice histogram, zebra stripes etc.

incident metering (not the dome), and *before* taking a photo.

The flat sensor cover one was included.

And if you don't trust digital cameras, how about a device which measure
the white balance of a scene, telling you how many Kelvin you have?

those exist too.
