Spectrophotometer UV-Vis

L-VIS-400

Single beam wavelength scanning in whole wavelength range of 320~1100nm.
Manual 4-cell holder accommodates long path length cells up to 100mm.
Optimized optical and electronics design ensure high performance and reliability.
Rich measurement methods: wavelength scan, time scan, mutli-wavelength determination, mutli-order derivative determination, double-wavelength method and triple-wavelength method etc., meet different measurement requirement.
Data output can be obtained via a printer port and a RS-232 interface (RS485 and USB port optional).
Parameters and data can be saved for user's convenience.
PC controlled measurement can be achieved for more accurate and flexible requirement.
