PA390  Wavelength range 190-1100nm Scanning Spectrophotometer 




Product Description




1. Large LCD screen (480*800) with 65 true color and support U disk data saving.

2. Imported and environmental deuterium lamp, preventing form ozone inhalation.

3. Data output: data can be exported to U disk(USB output)

4. Print port: instrument can connect PCL printer A4 paper(USB Port)

5. Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light.

6. Upgrade package can be downloaded from AOE web with S/N, support U disk one-key upgrade.

7. Real-time monitoring the lifetime of deuterium lamp and Tungsten lamp with advanced system.

8. Pre-aligned design ensures user can change lamps conveniently.

9. With GLP self-check function, check the wavelength accuracy and photometric accuracy, can provide test report and power-off protection.

10. Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically.

11. With SIO2 coating optical mirror, reducing the pollution form outside fully.


Basic functions:


1. Photometry(Basic)

Test Abs. Transmittance and energy by fixed wavelength.

2. Quantitative (Qty)

Linear fit and linear fit through zero two modes

A. Coefficient standard sample input and standard sample read three modes to establish standard curve

B. Establish A=k1*C+K0, can search original data, graph curve, parameters settings.

C. Can save 240 group curves, can test 240 data in each curve.

D. Double wavelength, triple wavelength test functions.

3. Kinetics(kins)

Used for time course scanning or reaction rate calculation A/t, can search all data.

4. Multi-wavelength(MultWL)

Can test transmittance and Abs. With 8 different wavelengths at most.

5. Spectrum (spec)

User can set the scan range from 190nm to 1100nm to test the max. Abs. Peak value, can do derivation, arithmetical operations to the graph.
