SP-1900 Series Double Beam UV-visible Spectrophotometer | | The SP-1900 is a double beam spectrophotometer. The SP-1900, which inherits strongpoint of all mature productions, and also uses the classic double-beam theory, makes the test result more precise, stable and reliable.
The SP-1900 is ideal to widely use most of test filed such as clinical laboratory, biochemical laboratory, pharmacy, petrol chemical laboratory, environmental protection and various fields of quality control.
This user’s manual provides the description of the SP-1900, a list of main specifications, functions introduction and usual operations. Available accessories.
This instrument is compact, easy-to-use, and ruggedness. The large sample compartment accepts various accessories and cell from 10mm to 100mm path length. The built-in RS-232 serial interface enables the instrument to be connected to a computer. | | SP-1900 series UV-Vis spectrophotometer includes 4 models totally. See table 1900 Series Spec |
