For replacement – please select AS2100 series laser
Superior Accuracy at Long Range
The AR2000 Laser Distance Meter can measure natural targets up to 100m (328 ft) away and retroreflective targets up to 500m (1640 ft) away with an accuracy of ± 1mm (0.04 in) depending on target reflectance and environmental conditions. The AR2000 can measure glowing hot targets up to 1500°C (2700°F), and it can operate in applications with bright ambient light. The maximum measurement frequency of the AR2000 is 100Hz in optimal conditions.
Laser Diode
The AR2000 has a Class 2, red, visible laser diode for simple aiming and setup. The spot size is 4mm as the light leaves the laser and 3mm at the focus of the beam at 5m with a divergence of less than 0.2mrad. Larger targets may be necessary at long distances.
Integrated Display
The AR2000 comes standard with a 3.5cm diagonal, monochrome, OLED screen with 4 membrane keys on its body that can be used to easily change common laser parameters and display measurement data in real time. (Please note that some parameters do require connecting to the laser from a serial port to change.)
Outputs and Inputs
All models of the AR2000 can communicate using RS-232, RS-422, or RS-485 serial protocols by adjusting a single parameter. The AR2000 also comes with a standard, 4-20 mA, analog, current loop output. The analog output can be programmed to have a custom measurement span, and the minimum and maximum currents can be set to any points in the laser’s range.
The AR2000 has a single limit output for indicating alarms. This can be useful for triggering an external device when a target reaches a set position. The AR2000 also has a line in to receive an external trigger to take single distance measurements.
