723N visible spectrophotometer

Vis Model: 723N Instrument: Applications are widely used in medical and health, clinical examination, biochemical, petrochemical, environmental protection, quality control and other departments. Product Description Main features: The instrument uses 5 \ "; LCD graphics display and an external display and thermal printer as an output device, clear displays test results and operation tips, thermal printer can easily print the test results data reports and save test method provides a photometer mode, wavelength scan, quantitative analysis, dynamic analysis and multi-wavelength test mode, providing a quantitative factor is entered in the test mode, a unique multi-point method and determined three common methods of analysis than cuvette pairing can eliminate cuvette pair cause measurement errors (valid only in the photometer models and quantitative analysis) with automatic zero / full scale adjustment function readings high accuracy, reproducibility and stability can best needs of different users, with different wavelength interval sampling 0.1nm, 0.2nm, 0.5nm, 1nm, 2nm, 4nm technical parameters:. ● Wavelength range: 325nm-1000nm ● Wavelength accuracy: ± 1nm ● Wavelength repeatability: ≤0.5 nm ● Spectral Bandwidth: 4nm ● Stray light: ≤0.3% (τ) (360nm Department to NaNO2 test, found 0.1% τ) ● transmittance range: 0.0% ~ 200.0% (τ) ● Transmittance accuracy: ± 0.5 % (τ) (NBS930D) ● Transmittance Repeatability: ≤0.2% (τ) ● absorbance display range: -0.301-4.000 (A) ● Baseline flatness: ± 0.005 (A) ● Drift: ≤0.004A / h
