Transmission Densitometer

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.
  • B&W transmission densities
  • Calculates positive and negative dot area (TBX1500)
  • Soft key menu operation
  • 7 inch throat to measure large samples
  • Readings are very repeatable with a large degree of accuracy
  • USB port standard

The IQ150 Densitometer, engineered with the latest in software technology, is so easy to use that an operator's manual isn't even needed! Yet, the affordable IQ150 fulfills your press and pre-press quality control needs with precision. It quickly and easily computes the main densitometric functions: density, density difference, dot area and dot gain. The IQ150 Densitometer has proven itself an indispensable workhorse for printers. No other portable densitometer available today can offer so much, so consistently, at so reasonable a price.
  • Available functions: Density, Density Difference, Dot Area and Dot Gain.
  • Simultaneous display of all filter densities: Shows the major filter value in large characters; the three minor values are shown smaller.

Portable Reflection Densitometer

The affordable RBP Densitometer measures black and white densities quickly, accurately and conveniently. With all the features and advanced electronics of its companion color model, the RCP, the Tobias RBP is ideal for measuring black & white densities of halftones for exposure prediction, checking D-Max and calculating dot area.

One-Hand Operation.No switches to turn on; no buttons to push. Power-on is automatic. Just position the target over your sample and press down the RBP housing to read density. To conserve battery power, the lamp shuts off after 2 seconds; the display remains on as long as RBP is held down on sample.

Rugged, Compact Design.Electronic circuitry and optical system are mounted on a firm, metal baseplate and protected by an unbreakable plastic cover. High strength, low mass design (a mere 14 oz.) that is built for years of tough pressroom use.

Long Battery Life.Thousands of measurement cycles on one 9V alkaline battery. A "LO BAT" signal on the display gives you plenty of warning when it needs replacement. An optional rechargeable NiCad battery and charger kit are also available.

Zero to Paper With Ease.A single thumbwheel FINE ZERO adjustment allows you to quickly offset zero to your paper base or adjust it to the calibration standard supplied with the RBP. The ZERO and CALIBRATE controls allow for periodic adjustment as well as to force conformity to another densitometer, if desired.
