Measuring distances, heights and angles has never been easier. The Vertex system comprises two separate components: a measuring unit and a transponder. The two components communicate using ultrasonic impulses: a technique that makes it possible to measure in very difficult surroundings and dense vegetation by “shooting” through bushes and leaves without difficulty! The system is designed for outdoor use and field environments. It works well in rain and low temperatures. Hypsometer specifications: Distance: 0-60 m / 0-197’ with a resolution of 0.1 m Angle: ± 100 % with a resolution of .5 % ± 90 degrees with a resolution of .1 degree Height: 0-100 m / 0-330’ with resolution of 0.1 m / 0.1’ Accuracy: ± 1 %
