- Deuterium halogen light source
- Measuring platform and analysis software included
- SMA 905 connection terminal
- Exclusive storage box
The SEC2020 spectrometer system is a spectrometer that enables various spectrometric measurements, focusing on spectroelectrochemical measurements. The high-performance grating and optical design, makes possible to measure with high sensitivity in a wide wavelength range, from ultraviolet to near infrared (UV/VIS/NIR), with a single unit.
For the light source, a compact modularized deuterium halogen lamp is used, which is fixed to the cell holder on the accessory platform for the measurement.
Furthermore, the spectrometer and the light source come with SMA905 connector, which makes possible to connect various optical fibers and probes, to construct the original measurement system.
Structure of SEC2020 spectrometer system
The SEC2020 spectrometer system consists of the following spectrometer, cell holder, light source, platform and collimating lens.
For spectroelectrochemical measurements and absorbance measurements, each instrument is fixed on the platform.
For measurement using immersion probe or optical fiber, you can use it by directly connection of the optical fiber to the spectrometer and light source.
The spectrometer is connected to a PC with a USB cable and controlled with Spectra Smart analysis software.
