1: General description
  The LS123 meter is a wide range spectral wavelength power meter. It can be used for
measuring the optical power density of UV light. It is used for

Evaluating UV Rejection property of the tint
of windows, solar films, glass and other
transparent materials ;
measuring the power of ultraviolet radiation
(260nm~380nm), gives visual and reliable
result ;
UV sterilization and curing;
General laboratory use;


3: Operation
3.1: Measure the UV power of solar or UV lamp
    Put the meter at a suitable distance, and direct the
end-mounted sensor to UV source, press the POWER key to
switch on, select the suitable range for the measurement, the
value will display.
3.2: Measure the UV rejection of solar control film, glass etc. it
will take measuring in 2 steps.
