The two detectors are used to measure sample and reference, respectively and simultaneously for optimizing measurement accuracy.

Lamp selection enables conserving the life of D2 tungsten lamp. Real-time clock for date time stamping of results.

Light Path Design : Double Beam

LMSPUV1900 double lightt design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

LONG PATH LIGHT DESIGN

LMSPUV1900 unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.

16MM OPTICAL BASE
LMSPUV1900 series use a rigid 16mm diecast aluminum base as their optical mount to ensure the stability and reliablity.

6 Inches LCD Display

LMSPUV1900 series have a 6A inches LCD display to show results and curves directly on the screen.
