The X-Rite 383 and 384 Sensitometers set a new standard of performance for x-ray processor quality assurance.

Their unique calibration monitor circuit helps assure higher accuracy and stability of the light source. As a result, you get more repeatable exposures from month to month and from instrument to instrument.

Choose either the 383 for single-side or the 384 for double-side exposure of control strips for x-ray and cine film processing systems. Each sensitometer is calibrated for commonly-used blue and green films. This makes them convenient for labs or clinics using more than one film type.

Because the sensitometers are compact, durable and battery-operated, they're handy as a lab or field instrument. An "on-off" switch prevents accidental battery drain when transporting the unit. a special low-battery circuit prohibits any exposing when battery voltage drops below the proper level.
