Tobias Transmission Densitometers Evaluate Films


IVYLAND, PA | Tobias Assoc. reports the new TBX1000 Series of black and white transmission densitometers measures ISO visual diffuse optical density (OD) to 6.00D. This wide measuring range reportedly allows evaluation of many types of film, laminates, and substrates.

The TBX1500 also calculates positive and negative dot areas while the TBX2000 measures percent opacity and transmission. The data can be uploaded to spreadsheets via the USB port using the optional “Data Capture” program.

To meet special requirements an optional filter carrier may be supplied allowing supplementary filters to be used to isolate a portion of the spectrum that may be of interest. The units can show deviations from a stored reference value for all functions. Optical system allows for repeatable readings of metallized films and many types of plastics.

Features include the following:

• Soft key menu operation

• Advance optical system to meet various industries’ specifications

• 7.5-in. throat to measure large samples

• Repeatable readings with a high degree of accuracy

• Optional band pass filter

• Standard USB port

• Software calibration

• Switchable LED table lamps
