Quick Selection Guide

UV Analysis: The UV-5100 and UV-5800 models are required for testing in the ultraviolet range (starting from 190nm).
High-End Precision: The 5800 Series offers the highest wavelength accuracy (±0.5nm) and superior stability for demanding research.
Automation: All models except the V-5000 feature automatic wavelength adjustment, saving time during multi-wavelength tests.
Wavelength Extension: The 5800 Series extends the measurement capability up to 1100nm for specialized NIR applications.

FAQs:

1. What is the difference between the 'V' and 'UV' series?
The 'V' series (V-5000/5100/5800) covers the visible spectrum starting at 320–325nm. The 'UV' series (UV-5100/5800) extends into the ultraviolet range starting at 190nm and includes an additional Deuterium (D2) lamp.
2. Which models feature automatic wavelength setting?
The V-5100, UV-5100, V-5800, and UV-5800 models all feature automatic wavelength setting. Only the entry-level V-5000 requires manual adjustment.
3. What is the spectral bandwidth of these instruments?
The V-5000 has a bandwidth of 4nm. All other models in the 5100 and 5800 series feature a narrower 2nm bandwidth for higher optical resolution.
4. Which model offers the highest wavelength accuracy?
The V-5800 and UV-5800 offer the highest precision with a wavelength accuracy of ±0.5nm. The 5000 and 5100 series provide an accuracy of ±2nm.
5. What photometric modes are available for testing?
These spectrophotometers support four primary measurement modes: Transmittance (T), Absorbance (A), Concentration (C), and Factor (F).
6. How do I export data from the spectrophotometer?
All models are equipped with both a USB port and a Parallel port to facilitate easy data output to computers or external printers.
7. What type of detector is used in these models?
Every model in the series utilizes a high-sensitivity Silicon Photodiode detector to ensure stable and accurate light measurement.
8. What is the concentration range for measurement?
The instruments can display concentration values (C mode) ranging from 0 up to 9999C, suitable for various laboratory concentrations.
9. Which series provides better baseline stability for long tests?
The 5800 series provides superior stability at ≤0.001A/30min (at 500nm), which is twice as stable as the 5100 series (≤0.002A/30min).
10. Does the wavelength range extend into the Near-Infrared (NIR)?
Yes, the V-5800 and UV-5800 models extend the wavelength range up to 1100nm, whereas the other models reach a maximum of 1000nm.
11. How is the stray light performance managed across the models?
Stray light performance improves with the higher-tier models, reaching a significantly low level of ≤0.05%T in the 5800 series for increased data integrity.
12. What are the power requirements for these devices?
The 5000 and 5100 series support a wide range of AC 85~250V. The 5800 series supports standard AC 110/220V at 50/60Hz.
