Description

Single-Step measurement of%Opacity, %Transmission, andTransmission Optical Density

The Tobias TBX2000™ TransmissionDensitometer/Opacity Meter measuresand calculates percent opacity, percenttransmission, and transmission opticaldensity. The unit has been designed foruser convenience and error-freemeasurement. There is no more need tofigure the percentages manually. Thedata can be uploaded to a spreadsheetvia the USB port using an optional datatransfer program (p/n A2128). To meetspecial requirements an optional filtercarrier may be used allowingsupplementary filters to isolate a portionof the spectrum that may be of interest.

The TBX2000 has been designed for user convenience and error-free measurement. Table illuminationfacilitates film placement and the entire operation requires only one hand, leaving the other free for notetaking or sample repositioning.
Plastic materials are easily read where both the percent opacity and the percentage of light that is nottransmitted through the material can be displayed. The unit can also display the density values whenrequired. The unit has both an absolute mode and a relative mode, which can be used for comparing themeasured values to a previously stored value for consistent process control.
