Visible Spectrophotometer - (sp1105)

Main features:
* novel designed auto-collimated light path with grating monochromator, 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.
