Gauge them remoter, somehow (11)

I believe the answer is:

thermometer

'gauge' is the definition.

'them remoter somehow' is the wordplay.
'somehow' indicates an anagram.
'them'+'remoter'='themremoter'
'themremoter' anagrammed gives 'THERMOMETER'.

(Other definitions for thermometer that I've seen before include "Device measuring temperature" , "Instrument for measuring temperature" , "Temperature measure" , "Temperature gauge" , "Temperature-measuring instrument" .)

I've seen this clue in The Mirror.
