Main characteristics:
1, the strong performance
of the instrument: excellent optical
system, advanced electronic systems, a
high standard of mechanical system,
ensure that the 0.010%T ultra-low stray
light;
2, stable and reliable
quality: double beam dynamic feedback
proportional recorded photometric system
ensure baseline stability; deuterium
lamp, photomultiplier tube and other key
parts are imported parts, to ensure that
the instrument is stable and reliable
and long life;
3, precise measurements:
the use of imported high quality
holographic grating, further reducing
apparatus of the stray light, making the
instrument analysis more accurate;
4, easy and efficient
human-machine dialog : Based on WINDOWS
design UVWin Chinese operating software,
provides a wealth of instrument control
and operation function. Easy to use,
flexible and efficient, easy to meet
user requirements analysis;
5, excellent scalability:
a peristaltic sampler, ultra trace pool
rack, thermostatic pool frame, optical
integrating sphere, specular reflection,
optical fiber attachment and cuvette
series such as a large number of users
optional special accessories, enables
the instrument to greatly expand the
scope of application;
6, simple and convenient
equipment maintenance: unique socket
type tungsten lamp and a deuterium lamp,
when changing the lamp is removed from
the optical debugging, the equipment
debugging, maintenance more convenient. |
