Introduction
* Can perform qualitative and quantitative analysis on sample substance in the range of VU and VIS spectrums.
* The instrument finds wild applications in medical and health, clinical inspection, biochemistry, petro-chemical industry, environmental protection, quality control, etc.
Characteristics
* Microprocessor measurement system. Accurate T-A changeover and Automatic 0 and 100 adjustment.
* Functions of GOTO l, time scanning, automatic 8 cell-holder, automatic-deduction of cell error, multi-point concentration calibration and setting of slop and intercept.
* RS-232 interface and parallel printing port.
* By means of RS-232 series interface and operating software, it will have a much wide measurement functions to perform all wavelength scanning, time scanning, concentration linear regression equation (the order of 1,2 and 3) and multi-wavelength measurement.
