The new series of TBX1000™ Black and White Transmission Densitometers measures ISO Visual diffuse Optical Density (OD) from 0.00D to 6.60D.  This wide measuring range allows evaluation of many types of films, laminates, and substrates. The enhanced optics were developed for measuring metalized films and many types of plastics with a high degree of accuracy and repeatability. The TBX1500™ also calculates positive and negative dot areas while the TBX2000™ measures percent opacity and percent transmission.

Click Here for information  on the NEW TBX1000C™ color transmission densitometer that measures color densities for Red, Green, and Blue filters. Custom filters,including for infrared or ultraviolet, can be used. 

The TBX1000C insures consistent process control in the manufacture for films, laminates, and substrates.

There has not been an accurate method for measuring transmission densities of metallized film.  The TBX1000 and TBX2000 transmission densitometers were specially developed to take into account the unique optical properties of metallized film. In addition, the TBX1000 series of densitometers will measure densities of a wide range of opaque and transparent materials. The units can handle materials that have densities as high as 6.60D with great accuracy and precision. By setting a density or opacity standard, your quality control department can evaluate the coatings on the film.
