Product Description
Introduction:The equipment is designed with sophisticated power protection system. With high capacity of internal memory, it can store testing results, scanned images, regression equations and correction data. Therefore, it follows a fast initialization when power The instrument can be connected with dedicated printer, which can print testing results, or draw curve from spectral scanning, fixed wavelength time-based scanning, and linear regression.There is a USB port on the device, and UVwin8 software is optional to order. The device can be connected to a PC, which can not only enhance the performance in data testing and spectrum scanning, but also expand the memory to save more testing results.Features:UV visible spectrophotometer adopts split beam survey optical system, and blazed holographic gratings. They have outstanding test precision and very competitive prices. With powerful functions, the equipment shows great performance in qualitative and quantitative testing, such as:1. Full-spectrum scanning2. Detailed spectrum scanning3. Time-based kinetics determination4. GOTO λ5. Linear regression6. Concentration direct reading7. Peak/Valley detecting8. Multi-wavelength measurement721/722 Visible SpectrophotometerIntroduction:The 721/722 visible spectrophotometer adopts advanced technology and design concept, featured by its modern appearance, outstanding data process and control ability.
