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, environment protection, food inspection, petrochemical, tertiary institutions, basic teaching experiments, etc.

 

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.
