Radian Plus

Wireless. Controllerless. Effortless.

Less is more. API presents a milestone in laser tracker innovation: The API Radian Plus laser tracker (formally known as The Omnitrac 2). The Radian Plus is smaller, lighter and easier to use than all other laser tracker systems of its kind and in its price segment. Moreover, it has no external controller, setting it apart from all other laser trackers on the market. This means: wireless, controllerless, and effortless.


The Radian Plus advances the portability and convenience of laser trackers. Radian Plus includes:

  • Completely wireless operation (Integrated controller, weather station, tilt sensor, battery, WiFi)
  • Battery operation (3-6 hours) with internal, rechargeable cells (non-removable by user)
  • High accuracy ADM able to do dynamic measurement
  • Autolock (Camera Assisted Automated Target Acquisition)
  • Onboard level sensor
  • Highly portable (only 10.8 Kg with a single transport case)
  • Mounting versatility: mount sideways, upside down, underneath, or directly on your part
  • Compatible with the current API quick-link instrument stands and accessories

Reliable in harsh environments

The Radian Plus laser tracker is the ideal measuring instrument for a wide variety of applications in industry, whether the work is indoors or outdoors. Its compact size and wireless design make it possible to measure in confined environments where other systems cannot go.

The Radian Plus is the only wireless laser tracker capable of dynamic measurements. It can measure up to 10 times faster than competing systems. Its rugged design and solid construction are a perfect fit for tough working conditions in any industry. The Omnitrac 2’s built-in battery allows up to 6 hours of continuous operation and there is an optional AC/DC connection as well.

Within a few minutes of starting up, the Radian Plus reaches about 90 percent of its accuracy. The Radian Plus measures up to 100 meters, in a temperature range of -4° to 104° (F) and weighs only 10 kilograms.

Everything built in. And more compact than ever.

Everything needed to measure with the Radian Plus is already built into the unit, including the controller, weather station, tilt sensor and battery. The Radian Plus transmits data via WiFi.

The Radian Plus uses ADM (Absolute Distance Measurement) technology to operate. It can be mounted and used in any position: overhead, perpendicular to a wall or inclined in space, beneath or inside a part.
