|Long-range distance measuring equipment for industrial and academic environments|
|Home > Products > AR4000|
AccuRange 4000 laser rangefinder is Acuity's fastest distance measuring
too for measuring long distances. Employing time-of-flight measuring
principles, the rangefinder can accurately gage distances up to 54 feet
Non-contact measurement is made simple with the three models within the AR4000 rangefinder series that have different laser diodes. All models are compact and durable, residing in a NEMA-4 enclosure for challenging industrial environments.
The AR4000-LIR laser rangefinder has a working range to 54 feet on light surfaces (85% diffuse reflectance, such as paper or light paint) or 35 feet on a 30% reflectance target with an accuracy of 0.1 inches. It uses an infrared 780 nm 8 milliwatt laser. This is the sensor of choice for best accuracy in most applications. An optional 20 mW laser upgrades is also available for the AR4000-LIR sensor for extended range to darker surfaces (54 feet on 30% reflectance) and in sunlight.
The AR4000-LV rangefinder has a working range of zero to 40 feet on 85% diffuse reflectance surfaces or 30 feet on a 30% reflectance target with an accuracy of 0.3 inches. It uses a visible 670 nm 5 milliwatt laser. This is the sensor of choice where a visible beam spot is required or your application must remain under and FDA Class 3B (EN 60825-1 Class 3B) laser category.
The AR4000-RET distance measuring rangefinder is used with reflective tape supplied with the sensor. It is a low-power, Class I eye-safe device, with an accuracy of 0.1 inches with a range of 2 to 54 feet. This is the sensor of choice where it is possible to apply the adhesive-backed retroreflective tape to the target surface, since this provides a strong return signal for optimum operation.
