Product Description

Visible Spectrophotometer 721

Application:

• This instrument is a standard equipment which based on the principle of spectrophotometry.
• It can measure transmittance or absorbency samples within 340nm – 1000nm wavelength range.
• Ideal for Clinical Sanitation, Biochemistry, Environment Protection, Food Inspection, Petrochemical, Tertiary Institutions, Basic Teaching Experiment, etc

Characteristics:

• Adoption of new single-chip microcomputer system, complete function, compact size, easy maintenance.
• 4 digital LCD Display.
• With flame retardant & insulation materials
• Easy 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 improved.
• To avoid energy plummeting after reflector was burnt, it has adopt lens to gathering light.
• With a professional lamp holder so that it can not be replaced the optical circuit of halogen tungsten lamp.
• Automatic calibration 0%(T),100%(T) & absorbency 0(A).
