Understanding Densitometers: Features and Vendors

This page covers the basics of densitometers and its benefits and describes features of densitometer from Fluke Corporation and other manufacturers.

Definition: A densitometer is a device that measures the degree of thickness or density of a material. This material can be semitransparent, transparent or a reflecting surface.

Essentially, a densitometer consists of a light source and a photoelectric cell. It determines the optical density of a sample material placed between these two elements.

Based on the material or surface being measured, there are two main types of densitometers:

• Transmission Densitometer: Measures the density of transparent materials.
• Reflection Densitometer: Measures density based on the light reflected from a surface.

Densitometers are commonly used in photography to measure the photographic density of images printed on film or prints. They are also used to calibrate printers and other printing equipment. Additionally, they can measure the saturation of a particular color in an image.
