Clinometer

Add to album

A clinometer is a surveying instrument used for measuring the angle of inclination. This brass example, also known as a drainage level, was made around 1855 by Gardner & Co. of Glasgow and retailed by H.A Thompson of Lewes in Sussex.

The clinometer (pictured here in its wooden case) has a telescopic sight, bubble level and silvered scale. Engraved on the scale is 'REGISTERED NO 2602 DEC 28TH 1850' and 'THOMPSON/ LEWES'.

T.R. Gardner registered the design of this special level - used when installing drainage pipes - in December 1850.
