FET 220
Short Description
Electronic theodolite with 20″ angular accuracy, a 30× telescope, absolute angle encoder and laser plummet. Designed for construction setting-out and horizontal, vertical and zenith-angle measurement. Article no. 313000.
Electronic theodolite for construction surveying
The geo-FENNEL FET 220 measures horizontal, vertical and zenith angles for site layout and civil engineering. A 30× telescope and absolute encoder provide 20-second angular accuracy, while the built-in laser plummet helps centre the instrument above a ground point.
Measurement functions
Horizontal readings can be held or reset to zero at a chosen position. Clockwise and anticlockwise measurement are supported, with vertical readings in degrees, gon or percentage slope. Display and telescope illumination assist in low light.
