Instrument Function:

l Photometric measurements: simultaneous measurements at a wavelength of 1~ 6 of transmittance and absorbance.

l Spectral measurement: in the wavelength range for transmission, absorbance and energy spectrum scanning, and various data processing such as peak and valley detection, derivative computation, spectrogram operation, etc.

l Quantitative measurement: single wavelength, dual wavelength, three wavelength and multi-wavelength measurement. 1 ~ 9 work curve (1 ~ 4 times) regression.

l Dynamic measurement: time scanning of transmittance and absorbency in any set of wavelengths and may carry on various data operations.

l Data output: can undertake data file and parameter file access; the measured results are output in standard data file format.

Main features:

l The newly designed excellent optical system, high-performance holographic blazed grating, to ensure the instrument of low stray light.

l Double beam metering system, with advanced circuit tt&c system, make the instrument with high stability and low noise.

l Automatic control systems, advanced design concepts to ensure that instrument with high reliability and stability.

l Removable structure of sample room design, easy to replace different attachments. To satisfy different analysis demand.

l Capacious open source chamber design, make the light source change more convenient.

l Key components are of high quality; guarantee the high reliability of the instrument performance.

l English and Chinese operating software under Windows environment, with much patent technology, provides abundant unique analysis capabilities.
