SP2000 Visible Spectrophotometer

Recommended application:

SP-2000 is a visible spectrophotometer special designed for micro amount sample. The sample compartment can hold cuvettes with100mm light path, and diversified cuvettes with light path at a range of 5-50mm also can be hold. SP-2000 is used as a teaching instrument in basis laboratories, which is used in colleges for specialty of environmental protection. It's also used as an instrument for products quality control at sugar-refinery, food and drink industry. It's better used as a monitoring device that controls the let of waste water in industries, such as electricity generating, water supply, paper making, plating, printing and dyeing, and so on.
Main features:

* The large sample compartment with long path detecting system, enable diversified cuvettes be hold at the range of 5-100mm.
* Novel designed auto-collimated light path with grating monochromatic, guarantees excellent optical performance.
* The SCM technology enables the instrument to be intelligent and digital.
* Function of 0%T and 100%T self-adjusting, which enables the operation simple and human.
* Large display with LCD, which enables the testing parameters, be displayed as transmittance, absorbance, and concentration.
* High precision of data processing that reaches one percent of a hundred thousand, which makes the transform between transmittance and absorbance with little error be possible.
* Filters auto-switching at the whole wavelength range, enables the instrument without additional manual operation.
* Switching power supply, with self-adaptive inputting voltage of 85~264VAC, (that is abbreviated to “SMPS”), guarantees that the instrument can work normally with different power supply at any environment.
