DESCRIPTION : The hand level is a small, economical level for use with preliminary surveys to determine travellerway or cableway steel work elevations and other feasibility type site reconnaissance work. The abney level is very similar to a clinometer in that it is used to measure the value of a slope by means of arc measure and grade percentage........ Size:- 7 inches / Color:- Yellow / Material:- Solid Brass. An Abney Level is a compact and versatile handheld instrument used in surveying, forestry, and outdoor activities to measure angles of elevation, depression, and slope. Named after its inventor, Sir William de Wiveleslie Abney, this leveling device is widely known for its simplicity and ease of use. The Abney Level typically consists of a sighting tube or peep sight, which acts as a telescope, allowing the user to aim at a distant target or object. The sighting tube has crosshairs or reticles that help in precise targeting. On the side of the sighting tube, there is a protractor scale that measures the angle between the line of sight and the horizontal plane. Attached to the sighting tube is a hinged vane or clinometer bubble, which is used to level the instrument. The clinometer bubble serves as a spirit level, ensuring that the Abney Level is held horizontally during measurements. To use the Abney Level, the user looks through the sighting tube and aligns the crosshairs with the target. Then, by adjusting the angle of the sighting tube and reading the protractor scale, the user can determine the angle of elevation or depression between the observer and the target. This information is valuable in various applications, such as measuring the height of a tree, the slope of the terrain, or the inclination of a surface. Abney Levels are compact and lightweight, making them easy to carry and use in the field. They are particularly useful for quick and approximate angle measurements, where high precision is not required. Additionally
