An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity 's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a ...Optical Survey prisms are a specially designed retro reflector, specifically a corner reflector, that is used to reflect the Electronic Distance Measurement (EDM) beam of a total station. The survey prism reflects the EDM beam back to its source with both a wide angle of incidence and with high precision. Prisms reduce the scatter of the beam as it is reflected back to the total which allows ...
