FAQs of Precision Colorimeter:

Q: How does the Precision Colorimeter select different wavelengths for analysis?

A: The Precision Colorimeter utilizes a rotating disc equipped with optical filters at specific wavelengths (420, 480, 490, 520, 540, 560, 600, 680 nm). You simply rotate the disc to select the desired analytical wavelength based on your testing requirements.

Q: What is the recommended process for calibrating the instrument before measurements?

A: Calibration is performed manually by inserting a blank sample (such as a solvent without analyte) into the cuvette holder. Using the keypad or push button interface, you set the instrument to zero (auto zero) before analyzing your actual sample to ensure precise and accurate readings.

Q: When and where is the Precision Colorimeter most effectively used?

A: This colorimeter is most effective in laboratory environmentssuch as chemical, pharmaceutical, and research labsfor measuring the color concentration of liquid samples. Its robust design and ambient light protection make it suitable for routine and rigorous analytical work.

Q: What are the advantages of the optical grade plastic/quartz cuvette holder?

A: Optical grade plastic and quartz cuvettes minimize light scattering and absorption outside the measurement wavelength, leading to enhanced accuracy and repeatability. This material choice supports clear, reliable transmission and absorbance measurements.

Q: How does the instrument protect against ambient light interference during operation?

A: The Precision Colorimeter features built-in ambient light protection, ensuring external lighting does not affect the measurement. This results in more consistent readings, even in variable lighting conditions found in many laboratory settings.

Q: What benefits does the overload protection feature provide for laboratory users?

A: Overload protection safeguards the tungsten lamp circuit, preventing damage due to power fluctuations or overuse. This enhances the safety, reliability, and longevity of the colorimeter, reducing maintenance needs and downtime.

Q: How can users benefit from the direct concentration readout and auto zero functionality?

A: The direct concentration readout allows instantaneous display of sample results, eliminating the need for manual calculations. Auto zero streamlines calibration, ensuring that measurements are both quick and accurate, which is beneficial for high throughput laboratory work.
