Made in Glasgow

Postcard of Clinometer.
© National Museums Scotland


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, probably by Gardner & Co., scientific instrument makers based in Glasgow.

The clinometer has a silvered scale graduated for 'RISE' and 'FALL' and inscribed 'W. GARDNER/ 56 GORDON ST/ GLASGOW'.

T.R. Gardner registered the design of this special level - used when installing drainage pipes - in December 1850. William Gardner, his brother, was in business on his own account at 56 Gordon Street, between 1856 and 1861.
