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.
