Visible Spectrophotometer (721/722)

Product Description

Application: This instrument is a standard equipment which based on the principle of spectrophotometry. It can be measured transmittance or absorbency samples within **0nm****0nm wavelength range. It can be widely applied to Clinical Sanitation, Biochemistry, Environment Protection, Food Inspection, Petrochemical, Tertiary Institutions, Basic Teaching Experiment, etc. Characteristics: 1. Adoption of new single-chip microcomputer system, completely functions, compact in size, easily maintained. 4 digital LCD Display. 2. With flame retardant & insulation materials as a skin. Novel in design, easily & safely operation. 3. To be avoid energy plummeting after reflector was burnt, it has adopt lens to gathering light. 4. With a professional lamb holder so that it can not be replaced the optical circuit of halogen tungsten lamb. 5. **1 with Automatic calibration 0%(T), **0%(T) & absorbency 0(A). 6. **2 with Automatic calibration 0%(T), **0%(T) & absorbency 0(A) and boasts "Concentration direct reading" & "Concentration factor "functions.With a RS**2 interface can be easily connected printer or computer.
