Digital Display Spectrophotometers
In the world of modern laboratory analysis, accuracy, consistency, and usability are essential. The Visible Spectrophotometer with manual wavelength selection, digital display, and RS232C interface is a dependable instrument tailored for applications that demand precise and reproducible photometric measurements. Designed with functionality and simplicity in mind, this spectrophotometer is an excellent choice for laboratories engaged in routine analysis, research, quality control, and educational training.
Built for Precision and Practical Use
At the heart of this Visible Spectrophotometer is a manually adjustable wavelength control, allowing users to fine-tune the desired wavelength using a convenient dial on the front panel. This feature is especially beneficial in academic settings where hands-on learning is vital or in laboratories where users may prefer manual control for specific experimental requirements.
The wavelength range spans from 320 nm to 1000 nm, covering the visible spectrum and extending slightly into the near-UV region, making it versatile for a variety of samples and testing needs. The spectral bandwidth of 4 nm ensures a good balance between resolution and light throughput, supporting accurate measurements across a wide range of sample types.
Efficient and Clear Digital Interface
Equipped with a digital LED display, the Visible Spectrophotometer offers real-time measurement readouts, enhancing user confidence and reducing interpretation errors. Whether reading absorbance, transmittance, or concentration, the clear visual feedback ensures that data can be read quickly and reliably.
The device also includes a direct concentration readout feature, saving time and simplifying workflows by allowing users to see concentration values without needing manual calculations. Additionally, it provides a concentration factor setting function, enabling customized calibration based on user requirements or specific testing protocols.
Reliable Connectivity and Data Management
In a laboratory environment, seamless data communication is crucial. This spectrophotometer comes equipped with both RS232C and USB ports, allowing users to easily transfer data to a computer for further analysis, reporting, or archiving. It also includes a parallel printer port, enabling direct connection to a printer for hardcopy results.
These interfaces make it easy to integrate the instrument into existing laboratory setups or data management systems. Standard software is included, giving users enhanced functionality, such as data logging, graphing, and exporting capabilities for advanced reporting.
Designed for Stability and Accuracy
This spectrophotometer offers a photometric accuracy of ±0.5%T and repeatability of ±0.3%T, ensuring that results are not only precise but consistent across multiple tests. The wavelength accuracy of ±2 nm and repeatability of ±1 nm further contribute to the overall reliability of the system.
A stability rating of ±0.002A/h guarantees dependable readings over extended periods, making this instrument well-suited for both short-term testing and long-duration experiments. With low stray light (<0.02%T), even highly sensitive measurements can be performed with confidence.
