LRB 20,000C LRB 20000C Long Range LRF is a professional bi-ocular laser rangefinder designed for ground surveillance, target observation and distance measurement up to 20 km. This rangefinder employs proven time-of-flight delay algorithm to ensure the highest accuracy and a single strong impulse to minimise exposure time. With an optional angular mount it can also measure horizontal angles and magnetic azimuth, and vertical angles. Result of distance measurement is displayed through the eyepiece and can be transferred for processing via computer output. This robust rangefinder can benefit geological and engineering surveying, construction and repair works, maritime navigation, meteorology, and other activities that require accurate long range distance measuring.   Product Features: Distance measurement up to 20 km First or last target selection   Day/Night digital LED?display Serial Port Specifications Magnification Field of view   Ranger Finder Distance measurement range, m Range measurement accuracy, m Diopter correction, visual channel Diopter correction, LED Display Pulse power Minimum eye safe distance, m Pulse width, ns Beam divergence, mrad Bidirectional RS-232 communication   Environmental Operating temparture rangem, C Water resistant Shock resistant   Miscellaneous Power supply Battery capacity, shots Dimensions, mm Weight, kg Weight with case and accessories, kg   7x 6.7° 100-20,000 ± 5 ± 5 -0.6 ... -1.5 15 mJ 2,000 6 0.6 V -40° ... +55° V V 12-14.5V DC or 22-29V DC 200 - 250 on single charge 225x215x110 2.5 17 Accessories   Framed lens Eye shield Coordinate converter Rechargeable battery   Software / Cables Special tools and spare parts Tripod (optional) Angular mount (optional)
