Optical multi-meter


Optical power meter and optical light source make up optical multi-meter.JF-H510 Optical multi-meter integrates functions of both optical power meter module, which installed dual wavelength and single output laser source. JF-H510 optical multi-meter can provide both functions of optical power meter and optical light source

It can also use independently, which can provide a convenient and low price for engineering testing people and technician.
