UV-Vis Spectrophotometer, Visible Spectrophotometer, Flame Photometer, Photometer, Spectrum Photometer, Optical equipments.
Application:
This instrument is a standard equipment which based on the principle of spectrophotometry.
It can be measured transmittance or absorbency samples within 340nm-1000nm wavelength range. It can be widely applied to Clinical Sanitation, Biochemistry,
Environment Protection, Food Inspection, Petrochemical, Tertiary Institutions, Basic Teaching
Experiment, etc.
Characteristics:
Adoption of new single-chip microcomputer system, completely functions, compact in size, easily maintained.
4 digital LCD Display.
With flame retardant & insulation materials as a skin. Novel in design, easily & safely operation.
Advanced optical system design, sealed grating monochromator. With scientific mouldproof &
eliminate of stray light technology so that its longevity, stray light, stability indicator, metering
accuracy are apparently improved.
To be avoid energy plummeting after reflector was burnt, it has adopt lens to gathering light.
With a professional lamb holder so that it can not be replaced the optical circuit of halogen tungsten lamp.
Automatic calibration 0%(T),100%(T) & absorbency 0(A).
