Double-Beam Visible Spectrophotometer XV-8, 1.8 nm Bandwidth (CAT#: STEM-AL-9044-ZJF)

The XV-8 is a double-beam visible spectrophotometer intended for high-stability visible spectrophotometry. It is designed to perform photometric, spectral scanning, kinetic, quantitative, and multi-wavelength measurements. The optical, thermal, or analytical configuration uses a double-beam monochromator with a 1200 lines/mm holographic grating. Operation is supported by a 7 in touchscreen, USB storage, Bluetooth output, and CSV data export. The instrument provides the measurement modes and data handling functions stated in the source. It can be integrated into visible-range laboratory analysis requiring reduced noise and baseline variation. The stated performance and operating limits are restricted to the source-provided specifications. Overall, the system provides a double-beam visible photometric platform.
