Handheld New 3 in 1 Optical Multi Meter(GLK411), Power Range: -70 To +10 Dbm, Wavelength Range: 800-1700 nm

GLK200 series mini Optical Power Meter and VFL all-in-onemachine series are controlled by single-chip microproces-sor but multifunction. It can be well protected by using embedded detector and laser. The whole machine has automatic shutdown function, three VFL modes, backlight display, wavelength memory function, user calibration, wide test range, lighting, RJ45 cable sequence and cable tracker test functions.It is mainly used for continuous optical signal power mea-surement, optical fiber link loss test and optical fiber line on-off test. It is widely used in optical cable construction and maintenance, optical fiber communication, optical fiber sensing, Optical CATV and other fields.
