Model 304 Digital Spectrophotometer (Electronics India Deep Vision):
Product Overview and Application:
The Model 304 Digital Spectrophotometer, part of the Electronics India (EI) Deep Vision (DVI) series, is engineered to be a highly economical, reliable, rugged, and accurate instrument tailored for the spectrophotometric analysis of various concentrations. It operates specifically within the visible wavelength range of 340 nm to 960 nm. This model is particularly useful for analysis and testing within Chemistry Laboratories, Pharmaceutical Industries, Colleges, and University Labs.
The instrument measures and displays output in three critical modes: Percentage Transmission (%T), Absorbance (Abs.), and Concentration (Conc.). The outputs are available on a clear 3 ½ digit Bright Red LED display.
Key Operational Features:
The Digital Spectrophotometer Model 304 incorporates several features designed for user convenience and reliable results:
• Dual Digital Display: The instrument utilizes a dual digital display, providing separate readouts for both Wavelength and measured Data.
• Direct Concentration Facility: It includes a dedicated facility for direct concentration measurement.
• Stability and Accuracy: The design ensures the instrument is highly stable and accurate for precise readings.
• Versatile Sample Holder: The Model 304 includes a sample holder designed for 10 mm Test Tubes (often supplied as glass square cuvettes) and features an additional provision for using 50 mm Test Tubes (or glass square cuvettes), supporting various path lengths.
Optical and Technical Components:
The core optical system of the Model 304 is robust:
• Light Source: The light source utilized is a 6V, 10W, Tungsten Halogen Lamp.
• Detector: Measurement is handled by a Silicon Photodiode.
• Monochromator: The instrument uses a 600 line/mm Holographic Grating for effective spectral separation.
