FAQ for Visible Spectrophotometer NVS-200
1: Can data be easily saved and transferred?
Yes, the Visible Spectrophotometer supports USB data transfer in Excel format and includes internal memory to store up to 2000 data entries or 95 curves. This helps manage and share results conveniently without external software.
2: What types of measurements does the Visible Spectrophotometer NVS-200 support?
The Visible Spectrophotometer supports multiple working modes including transmittance (T), absorbance (A), concentration (C), and energy (E). This flexibility allows for a range of test types with one instrument.
3: What kind of grating is used in the optical system?
Our Visible Spectrophotometer uses a high-efficiency holographic grating with 1200 lines/mm, ensuring accurate spectral dispersion and measurement. This contributes to high-quality optical performance.
4: What maintenance does the Visible Spectrophotometer NVS-200 require?
The Visible Spectrophotometer requires minimal maintenance thanks to its robust design and reliable components. Routine cleaning of the cuvette holder and periodic lamp checks are usually sufficient to keep it running smoothly.
5: What is the noise level during measurements?
The noise level is very low, ?0.15% transmittance, which means the instrument provides stable and clear readings even for low-concentration samples.
