clinometer(redirected from clinometers)
Also found in: Dictionary, Thesaurus, Medical, Wikipedia.
a very simple geodetic instrument that is used to measure the slope angles of a terrain. A typical clinometer (see Figure 1) consists of a circular metal casing (1) and a sighting tube (2) that is fastened to the casing. The casing contains a graduated disk (3) on a spindle; attached to the disk is a weight that hangs
plumb, keeping the disk in a constant position. Other forms of clinometers are also available. The precision with which slope angles are determined by means of a clinometer does not exceed 0°.2.
