X-Rite 391 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 391
X-Rite 391 CD Manual
X-Rite 391 Power Supply
X-Rite 391 Interface Cable.
Serial to USB Conversion Kit
The 391 instrument contains twelve channels that allow you to monitor up to twelve different processors
The 391 also saves the measurement data of the last 32 strips measured for each channel.
The measurement data for each strip includes 21 steps of density, time/date, and temperature.
Temperature must be entered manually.
• (391 instrument only) Reference data can be entered manually or automatically.
• 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. • Provides Trend detection and warning.
• (391 instrument only) Contains Automatic Step Selection – identifies Mid Density, High density and Low Density according to the American College of Radiology Mammography Quality Control Manual definition.
• (391 instrument only) Provides networking capabilities when used in conjunction with commercially available networking processor QA programs, (ex. X-read Net). The densitometer uses an external modem to transmit measured data.
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.
