Record temperature and take off (4)
I believe the answer is:
tape
'record' is the definition.
(taping is a kind of recording)
'temperature and take off' is the wordplay.
'temperature' becomes 't' (abbreviation).
'and' says to put letters next to each other.
'take off' becomes 'ape' (I've seen this before).
't'+'ape'='TAPE'
(Other definitions for tape that I've seen before include "Fabric strip; record" , "Measure" , "The winning runner breasts the ...." , "Race finishing line strip" , "Strip of material (that might be red!)" .)
