Description
Verschoyle clinometer
Designed by Mr W.D. Verschoyle, “a mining engineer of great experience”, this instrument measures inclination and azimuth angles. To measure an incline the object is sighted, the spirit level (mounted inside the circular box) is viewed through the prism, and the bubble centred by rotating the box. The inclination is then read on the graduated scale and the vernier scale.
