Surveying Instruments  What are Surveying Instruments?  Types of Surveying Instruments  What are Surveying Instruments  Surveying Instruments are used for precisely measuring the earth’s surface. Surveying instruments are typically used for large scale outdoor projects from determining property boundaries, preparing construction sites or leveling earth but there are also surveying instruments that are used to measure environmental factors, locate underground services and as safety precautions.  Types of Surveying Instruments  Borescope   A borescope is an optical device that is made up of a flexible or rigid tube with an eyepiece/camera on one end. The camera is linked together by an optical or electrical system in between.  Borescopes are a non-destructive surveying instrument that are used to inspect an object for defects or imperfections without causing any damage. Borescopes are used to inspect industrial systems such as; pipes, heat exchanger tubes, welds, manufactured or machine parts and turbine engines. GNSS GNSS stands for Global Navigation Satellite System and is a satellite navigation system that uses small satellites to pinpoint the geographic location of a user’s receiver. The most common type of system to pair with a GNSS is a receiver. GNSS’s are generally used in the survey industry.  GNSS Receivers convert signals from visible satellites into a position on Earth. The number of visible satellites is dependent on the number of satellites the receiver is compatible with. Multimeter  Multimeters are an essential electronic testing tool that electronic technicians and engineers should own. As its name suggests, it has multiple functions including measuring voltage, current and resistance. It can also be used to test continuity between two points in an electrical circuit.  The use of a multimeter is paramount in order to prevent electrical hazards in industrial warehouses and similar facilities, like short circuiting or wires overheating.      Image cr
