ESICO - Model 2305 -Microprocessor Visible Spectrophotometer

FromEnvironmental & Scientific Instruments Co.

SHARE

Microprocessor Spectrophotometer is a solid state microcontroller based instrument designed for quick and accurate spectrophotometric analysis of any concentration. It operates at a wavelength range of 325 nm to 1000 nm. The output is available on a 4 Digit seven segment bright red LED display in terms of %Transmission (%T), Absorbance (Abs.), Concentration (Conc.) and Kfactor. The instrument uses the latest microprocessor technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility.
