Electronic Distance Measuring Equipment

Normally these used to measure long distances within 100km with their frequency range.

Electronic distance measuring equipment. Edm is commonly carried out with digital instruments called theodolites. Electronic distance measurement edm is a method of determining the length between two points using electromagnetic waves. Mileseey laser measure 229ft m in ft digital distance meter laser measurement tool with electronic angle sensor backlit lcd pythagorean mode measuring distance area and volume. The electronic distance measuring equipment is differentiated into three types as microwave instrument infra red equipment and light wave equipment.

The light from the laser bounces back to the device and the tool uses the time it takes for the light to return to calculate the distance that the laser traveled. We would like to show you a description here but the site won t allow us. The resulting measurement is often shown on a digital screen on the device. Edm instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers.
