Leica Absolute Tracker - AT401

The Leica Absolute Tracker AT401 is a portable coordinate measuring machine that ensures high accuracy even over very long distances

The Leica Absolute Tracker AT401 is a portable coordinate measuring machine that ensures high accuracy even over very long distances. 
Its power is provided by an internal battery and it can operate in very harsh environments, whilst maintaining the maximum precision and the most accurate volume measurement. 

The constructive "All in One" solution means an all-inclusive system with full accessories such as live video, gravitational levelling, environmental monitoring and integrated infrared remote control. Thanks to the communication system and Wireless integrated LAN, the Laser Tracker can be used in a completely wireless environment, making AT401 the most portable Absolute Tracker ever.

Specifications
All accuracies refer to Leica Geosystems 1.5 '' precision reflectors red ring (supplied with each sensor) to the point of 2/2 measurement mode in stable environmental conditions. 
The Full range is specified between 1.5 and 80 meters from the tracker within a vertical range of +/- 45 °. 
All accuracies are stated in maximum permissible error (MPE). 
Typical results are half of MPE in the order.
