Leica Absolute Tracker AT403

New all-in-one large-volume laser tracker system that sets a new standard for portability, simplicity, robust construction and measurement efficiency.

An all-in-one metrology solution more portable than any other on the market, the Leica Absolute Tracker AT403 from Hexagon Manufacturing Intelligence is a self-contained measurement workshop inside a compact and convenient single case.

With outperforming measurement process speed, operational simplicity like no other laser tracker and an unmatched level of robust construction, the Leica Absolute Tracker AT403 is a calculated bundle of affordable innovation without equal on the portable measurement market.

Improvements include faster and more economical stationary and continuous measurement processes, along with a streamlined station change procedure. Added WiFi access point functionality and hot-swappable batteries deliver unmatched measurement freedom. Designed for leading results in almost any imaginable measurement environment, it is rated for operation in temperatures ranging from -15 to 45 degrees Celsius and features built-in environmental monitoring, orient-to-gravity functionality and construction in line with the rigorous IP54 certification standard.

The Perfect Partner for the Leica B-Probe
The Leica Absolute Tracker AT403 presents the ideal solution for portable probing applications when paired with the established quality of the Leica B-Probe portable probing tool. This single-case portable probing system delivers improvements in measurement process speed and usability as well as customisable hidden-point reach. When added to the already class-leading cableless functionality of the Leica B-Probe, large-volume probing is now simpler and better than ever before.



All-in-One Integrated Design
From integrated wireless connectivity, environmental monitoring and all-day battery power, to overview camera, RapidSight aim scope and ergonomic carry handle, every need is built in.

Single-Box Probing System
Just one case contains the lightest and most portable sensor and probe as well as IR remote, with various transportation cases for full flexibility.

Smart Connectivity
Built-in WiFi with true access point functionality delivers single-user operation through simple PC setup and remote control options via laptops, tablets or smartphones.

Automatically re-establishes interrupted line of sight within a wide field of view with no user interaction required.

Continuous Measurement
Continuous time and distance measurement mode.

Entry-Level Probing
Cableless, battery-powered Leica B-Probe with customisable hidden-point capability.

IP54 Certification
The IEC-certified sealed unit guarantees ingress protection against dust and other contaminants, enabling effective measurement in even the harshest environments.

Integrated environmental unit monitors conditions including temperature, pressure and humidity to compensate for changes and ensure accurate measurements regardless of external factors.

Enables measurement with the Z-axis aligned to gravity, ideal for levelling and alignment tasks.

Battery Power
Independent hot-swappable battery power supply allows for quick and easy cable-free setup and all-day wireless operation.

Operating Temperature
Wide operating temperature range of -15 to 45 degrees Celsius.

Measurement Volume
Ultra-large measurement volume of up to 320 metres (ø), with minimum measurement distance less than 0.8 metres.

Hexagon Guarantee
Full 24-month factory warranty and guaranteed ten years of serviceability.
