Application:
722 Visible Spectrophotometer is a latest design following the Model 721.
It is a standard instrument which based on the principle of spectrophotometery.
This instrument can be measured the transmittance, absorbency & concentration
direct reading of samples within 340~1000nm wavelength ranges.
Meanwhile, it can be easily connected printer or PC process.
This instrument can be widely applied to clinical sanitation, biochemistry,
environment protection, food inspection, petrochemical, tertiary institutions,
basic teaching experiments,etc.
Characteristics:
Adoption of new single-chip microcomputer system, completely functions.
4 digital LCD Display, widely measurement range, higher accuracy.
Thin-film-style keyboard, dust-proof, waterproof, & easy to clean.
To be avoid energy plummeting after reflector was burnt, it has adopt lens to gathering light.
With a professional lamb holder so that can not be replaced the optical circuit of halogen tungsten lamb.
Automatic calibration 0%(T),100%(T) & absorbency 0(A).
Boasts "Concentration Direct Reading" & "Concentration Factor "functions.
With a RS232 interface can be easily connected printer (Optional).
