Zhengzhou 10MW red pen where to buy the best quality? [Zhengzhou] Emi Instrument 0371 -55,676,313 Website: www.hm5117.cn red pen red pen also called pass light pen, pen red light, visible light detection pen, fiber fault detection, optical fiber fault locator, etc., most for the detection fiber break, currently at their shortest detection distance is divided into: 5Km, 10Km, 15Km, 20Km, 25Km, 30Km, 35Km, 40Km and so on. Features: QW LD as the light source and MOD CW mode FC, SC, ST universal interface detection distance power output stable output red laser visible to human eyes. Strong penetrating power, fault light leaking through 3mm PVC layer remains clearly visible Nanotechnology multi-static protective shell rugged pen design, portable and easy to use features: fiber breaks and bending fault locating faults within OTDR dead-end fiber identification check point mechanical splice optimize applications: telecommunications, CATV engineering and maintenance of integrated wiring construction and maintenance of optical fiber device production and research projects other technical indicators: source wavelength 650 +10 nm singlemode model BW10-T/G/H output power 1/5/10/15/20/25/30/35/40 / 45/50 mW power 2 on the 5th battery power Continuous working time ≥ 10h detection distance (SM) ≥ 5/8/10/15/20/25/30/35/40 Km Operating temperature -10 ~ +60 ℃ ( no condensation) Storage Temperature -40 ~ +85 ℃ Housing Material Copper Alloy, Stainless Steel Dimension φ24 × 170mm (excluding interfaces) Weight Approximately 160g (without batteries)
