The NK282 series optical multimeter product adopts a high-sensitivity detector and is controlled by a single-chip microprocessor. The body shape is novel, and the design meets the requirements of human functionality, making it beautiful and durable. The optical power meter and red light use embedded detectors and lasers, which can provide good protection. The whole machine is equipped with optical power meter/light source, RJ45 line sequence, flashlight, etc. It also has optional functions such as visible red light source and RJ45 line finding. It is mainly used for continuous optical signal power measurement, fiber link loss testing, and fiber optic line continuity testing. It is widely used in optical cable construction and maintenance, fiber optic communication, fiber optic cable sensing, optical cable TV and other fields.
