Product Description

X-Rite 390 Process Optimization Densitometer. 

Excellent condition & clean , No loose power jack, No cracks, etc.
Self Calibrates fine and very smooth/quiet, Unlikely to find a better condition unit.
Comes from a very clean professional work environment that closed down.

         This auction include the following:
            X-Rite 390
            X-Rite 390 CD Manual 
            X-Rite 390 Power Supply
            X-Rite 390 Interface Cable.

Film strips are automatically measured using a motorized control mechanism. Data is sorted and available for viewing or transmitting. 
Operation is performed using 4 keys and has an interactive 16 character/2-line Liquid Crystal Display. 
the 390 instrument contains four channels). Stores each measured density value as an absolute density value. These density values can be viewed as absolute density values or as values deviated from their reference values. 
Comes preset with common process control equations used for interpreting data. 
Basic equations types are: Density at step number, Exposure level at density, Density at exposure level, Density Difference (Contrast), Gradient, and Mid Density (Speed).
Contains an editor function that permits you to set the Aim Values, Control Limits, Channel Names, and Equation formats that best suit your individual requirements. The Editor function also permits copying the setup of one channel to another channel. This is most useful when multiple processors of the same type are in use. The editor function can also be used to delete an individual unit or an entire database from a channel. Setting the Aim values and Control limits informs the densitometer when to display Go/No Go indications. After each measurement the unit displays if the limits were exceeded. 

The 390/391 densitometer is designed to measure film that has been exposed by an X-Rite sensitometer. The sensitometer uses a 21-step light modulator and a known quantity of light to expose the film. The maximum amount of light is emitted from Step No. 21. Each successive step emits approximately 70.7% of the light emitted from the step adjacent to it (.15 log exposure). The film responds to this exposure in a predictable manner called the D-Log E Curve, (Density-Log Exposure Curve). The following figure shows the response of a typical radiographic film exposed by a sensitometer. The portion of the curve that changes most with variations in processing is called the "straight line portion" of the curve.
