Introduction:
VIS721/722 are basic laboratory instruments which based on the principle of spectrophotometery.
It can be measured the transmittance, absorbency, concentration factor & concentration direct reading of samples within 340-1000nm wavelength ranges.
Meanwhile, it can be easily connected printer or PC software. It can be widely applied to clinical sanitation,
biochemistry.
Characteristics:
v Adoption of new single-chip microcomputer system, completely functions.
v 4 Digital LCD display, widely measurement range, higher accuracy.
v Thin-film-style keyboard, dust-proof & waterproof skin and easy to clean.
v To be avoid energy plummeting after reflector was burnt, it has adopt lens to gathering light.
v With a professional lamb holder so that can not be replaced the optical circuit of halogen tungsten lamb.
v Automatic calibration 0%T, 100%T & absorbency 0A.
