JK-UVS-757CRT UV-Vis Spectrophotometer
Profile:Manufacturer - Producer|Ref:PSL121249YH | Country: China | Currency: usd | Export: No
The instrument finds wild applications in medical and health, clinical inspection, biochemistry, petro-chemical industry, environmental protection, quality control, etc. It is a common analytical instrument used in physics and chemistry lab, can also be used in soil for available phosphorus, boron, nitrate, total phosphorus detection in plant
Can perform qualitative and quantitative analysis on sample substance in the range of VU and VIS spectrums.
Rapid adjustment (adjustable time is less than 3S).
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 ,and greatly expand measuremet function (except the mainframe function) and provide transmission of test data to EXECL, meet the user’s requirements for post-processing.
