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.   The TBX1000C and the TBX2000C have the same functions as the TBX1000 and TBX2000 with the additional capability of using filters.

Send in your densitometer for service every two years to ensure that your Tobias densitometer will maintain the functionality of a brand new unit.  A full calibration will also be performed and a Certificate of Compliance will be issued.  This program will meet most ISO9000 specifications.  All calibration standards are certified for one year.  They should be replaced (transmission units) or recertified (reflection units) yearly.
