A laboratory densitometer is a precise instrument used to measure the optical density of materials, such as films, liquids, and other samples. It works by analysing how much light passes through or is absorbed by a sample, offering valuable data on thickness, concentration, or uniformity. Commonly used in medical imaging, material science, and printing industries, densitometers ensure quality control and accuracy in applications like radiography, colour calibration, and chemical analysis. With the ability to deliver highly accurate measurements, laboratory densitometers are essential tools for researchers and technicians in various scientific and industrial fields.
