Device for measuring and recording (5)
I believe the answer is:
meter
'device for measuring and recording' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for meter that I've seen before include "Something measuring" , "Measuring device as for electricity consumption" , "Measuring device, say for electricity usage" , "Instrument for measuring quantity" , "Device that measures, say, electricity usage" .)
