We’re lighting up a dull Tuesday with a test of the old grey brain cells...

This picture has FIVE pieces of office tech that need to be PAT Tested. Can you guess what they are and what PAT Tests they require?

Office PAT Testing ItemsHint: Before you guess – take a second look, as there are only FIVE, not SIX – find the odd one out for an extra PAT Testers Point.

Post your answers on Twitter to @pat_testers or comment below for the chance of a shout out on Friday when we post the answers, good luck!
