scanning function spectrophotometer
Introduction
754 UV-VIS spectrophotometer is manual wavelength/ automatic scan spectrophotometer. With advanced technology and design concept, it incorporates modern appearance, outstanding data process and control ability. It is extensively used in the field of mining and factory, hygiene and medicine, and environment protection and labs etc. We are dedicated to offer high quality analytical devices for our clients.
Characteristics
« Novel designed monochromator with excellent optical performance; holographic grating of 1200/mm reduces stray light of the instrument.
« Narrower spectral bandwidth offers superb accuracy and precision, suitable for medical science analysis.
« The SCM technology enables easy operation; 0%T and100%T can be adjusted with one touch of a button.
« Four photometric modes: T,A,C,F,provide ease of use.
« LCD display is easy to read; large specimen chamber enables function extension.
« 754 E auto-wavelength positioning provides for precise measurement.
« Equipped with scan software, 754PC enables variable data processing of spectral & time scan, photometry determination and quantitative scan etc.
« Quantitative determination:
1. Standard curve is established by sample measuring, and then used for sample test; up to 100 calibration curves can be stored for late use;
2. Coefficient method: C=KA+b, enter the coefficient into formula for sample concentration test;
« If convenient, download the latest program from internet to upgrade the device.
