Antique Sestrel Clinometer

Here we have an antique sestrel clinometer, produced by Sewill & Davis and the Henry Browne & Son company. “Sestrel” is the trademarked brand of Henry Browne – created by taking the first 2 letters of “sensitive”, the first 2 letters of “steady” and the first 3 letters of “reliable”. Sewill & Davis began producing nautical marine instruments in 1838 and the Henry Browne & Son company has been around since the 19th century as well. You can learn more about Henry Brown and Son LTD. by clicking HERE.

This item is made out of solid brass and weighs 3.2 pounds. The diameter of the clinometer face is 5.75 inches, while the diameter of the mounting plate is 8 inches. If mounted to a wall, the clinometer’s face will extend out 2.25 inches and the knob on the face will extend out another 0.6 inches from the previous measurement.

A clinometer is a tool that is used to measure the angle of elevation, or angle from the ground, in a right – angled triangle. You can use a clinometer to measure the height of tall things that you can’t possibly reach to the top of, flag poles, buildings, trees.
