FAQ

Yes. Wavelength scanning is a dedicated N2S function, with Fast, Medium and Slow scanning speeds.

The specified stray light is ≤0.1%T at 360 nm using NaNO₂.

Yes. A thermal printer is built in for direct printing of test results.

Yes. The N2S supports kinetic time scanning.

Yes. Direct concentration readout and linear regression are supported.

The sample compartment supports 5–100 mm path-length cuvettes.

Yes. It has a USB communication port, and optional UVWIN8 software is available for PC-based data processing.

Both models support automatic wavelength setting, quantitative analysis and kinetic analysis. The N2S additionally provides wavelength scanning and a built-in thermal printer.

The specified wavelength range is 325–1100 nm. If your analytical method requires deeper ultraviolet wavelengths below 325 nm, select a dedicated UV-VIS model.
