341 Portable Transmission Densitometer

The 341 Portable Transmission Densitometer concentrates the best features of a tabletop densitometer inside a compact, portable, and economical hand-held unit. We designed the 341 as a completely self-contained instrumentable to take measurements anywhere you need.

A Solid Performer
Unlike some inexpensive densitometers, the X-Rite 341 includes a calibrated, internal light source. It meets global standards for geometry of a transmission densitometer, including proper diffusion of the light source , enabling true measurement values. Don’t be fooled by devices that claim to measure accurately from an external light table. Use the 341 – a truly portable, self-contained densitometer with all the functions you need.

The 341 measures density and dot area with extraordinary accuracy — in fact, it’s capable of measuring densities greater than 5.0D. The model 341 includes a calibration reference that is traceable to ISO standards for transmission densitometry. You can be assured of density and dot measurements made with the 341, no matter where you are .

The 341 also includes a built-in, back-lit film viewing table. This feature will help you quickly and easily locate the pro p e r measuring area of your film. Once you make your measurements, the high-contrast, LCD display of the 341 shows the measured density or dot area values.

Density and Dot Area Applications
The 341 can be used to make dot area and density measurements quickly and easily. The density function is useful for evaluating and setting the exposure of any imagesetting system, positive or negative. Use it to verify the DMax of your films, ensuring lightblocking film properties when making proofs or printing plates.

The dot area function is useful for verifying screen tint values from contacted films, duplicate films, or originals. It can zero on the film base, and accurately measure from 0 to 100 percent. It is handy and easy to use in linearizing or calibrating the tone value of any imagesetter.

361T Desktop Transmission Densitometer

The X-Rite® 361T sets the standard in transmission densitometers.Thousands of desktop publishers, service bureaus, trade shops and printers rely on the 361T to monitor the quality of their film output. It delivers unsurpassed versatility and accuracy.Whether you’re using the 361T for imagesetter linearization, exposure adjustment, processor quality control, or verifying duplicated or contacted films, you can be assured that you’re getting the best possible results.

Versatility
The 361T is the only densitometer to make accurate density and dot area measurements from your films. It was designed especially to allow instrument calibration to a known density reference and calibration to a known dot reference as well. The 361T is unique because it has a built-in UV response mode for measurement of otherwise invisible film base fog. An ordinary densitometer is not sensitive to UV blocking that can occur in the seemingly clear film base. The UV response of the 361T can also be used to evaluate diazo films which are commonly used in the production of electronic circuit boards.

Automation Options
Using an RS232 interface you can record readings directly into a spreadsheet for quality control analysis. It is also possible to transmit data directly to your RIP to automate your calibration process.
