Features: Single beam wavelength scanning in whole wavelength range of 320-1100nm. Three options for spectral bandwidth selection: 5nm, 2nm and 1nm, made according to customer’s need and satisfy the requirements of pharmacopoeia. Standard manual 4-cell holder accommodates cells from 5-50mm and changeable long path length cell up to 100mm. Optimized optics and electronics design, light source and detectors from the world famous manufacturer ensure high performance and reliability. Rich measurement methods: wavelength scan, time scan, multi-wavelength determination, multi-order derivative determination, double-wavelength method and triple-wavelength method etc., meet different measurement requirement. Data output can be obtained via a printer port. Parameters and data can be saved in case of power failure for user’s convenience. PC controlled measurement can be achieved via RS-232 interface (USB port) for more accurate and flexible requirement.
