These table top densitometers display transmission density and density difference. The TBX1500 also calculates positive and negative dot areas.

 

Single-Step measurement of Transmission Optical Density and Optical Dot Area

 

The Tobias TBX1000™ and TBX1500™ Transmission Densitometers measures transmission optical density. The TBX1500 also calculates positive and negative dot area. The unite have been designed for user convenience and error-free measurement. The data can be uploaded to a spreadsheet via the USB port using an optional data transfer program (p/n A2128). To meet special requirements an optional filter carrier may be used allowing supplementary filters to isolate a portion of the spectrum that may be of interest.The TBX1000 and TBX1500 have been designed for user convenience and error-free measurement. Table illumination facilitates film placement and the entire operation requires only one hand, leaving the other free for note taking or sample repositioning.The unit has both an absolute mode and a relative mode, which can be used for comparing the measured values to a previously stored value for consistent process control.
