WebMay 31, 2024 · A densitometer measures the absence of reflected light. … A spectrophotometer uses a series of filters or a prism to measure the wavelength of color in nanometer increments. These precise measurements create a spectral curve for the color and every color has it’s own unique spectral curve. What does a photometer measure? … WebA photoelectric detector to measure the transmitted light and convert that value into electrical output; 2. Photometers are designed to measure multiple ion types and are thus equipped with filters able to isolate multiple (often up to 5) wavelengths of light. Beyond the multiple wavelengths, photometers operate much like colorimeters.
