Laser pointing device - Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City (Tel: 0538-6290929, Website: www.tahnjd.com) ultra-long-range 1500 meters, spots of less than 50 mm, 35 mm spot at 1000 meters without drift, factory spots calibrated, users do not need to adjust the spot. Coarse aspect to rotate 360 ??degrees, fine-tuning is very delicate. Fast and easy installation, suitable for bolt diameter 16 to 24, can use a single bolt can be double bolt. AC and DC power supply with soft start and various protection functions, the input voltage range 24V ~ 260V output voltage (3 ± 0.05) V, under no circumstances can be used directly 24V AC over DC power supply. Truly long range, small spots, high brightness, dual power, wide voltage, soft start, long life, beautiful appearance. Domestic initiative, exclusive production, domestic and laser pointing device is currently in the boutique (national patent ZL 2008 2 0237518.7). The main parameters: Effective range: 1500 m spot diameter: 200 meters at 5 mm; 400 m at 15 mm; 600 m at 20 mm; 800 m at 30 mm; 1000 m at 35 mm; 1200 m at 40 mm; 1500 meters at 50 mm.
