|Fluke Bio-Medical Hand-Held Dual Color Electronic Sensitometer.|
Helps maintain optimum film processing conditions.|
This compact, precision instrument is ideal for maintaining consistent, high-quality film processing. By evaluating control films on a daily basis, the technologist can identify processor variations before they affect clinical radiographs. Also, processing conditions in multi-processor departments may be standardized. In the past, this was difficult in departments using varied film-screen combinations in different areas. With this sensitometer, proper exposure of either blue- or green-sensitive x-ray film is easily accomplished, with no need for internal adjustments.
Nuclear Associates' Hand-Held, Dual-Color Sensitometer features a 21-step density wedge with 0.15 D increments. The 21 density-gradient steps are numbered for convenience. An innovative, dual-color, electroluminescent light source provides precisely-controlled repeatable exposures. The desired color is selected with a front-panel switch.
To make an exposure, the platen is raised and a sheet of film is inserted beneath it until the film stops are reached. The platen is lowered and the exposure switch is depressed. An audible buzzer is activated during the exposure. To prevent double-exposures, a two-second delay is engaged before the next exposure can be made. When battery replacement becomes necessary, the unit will not expose film. Battery life is approximately 10,000 exposures.
Processor variations are monitored by comparing the control film to previously processed films.

|The Little Genius Scanning Densitometer.|
The 07-444 "Little Genius" Scanning Densitometer stands head and shoulders above all other densitometers when it
comes to performance, reliability and economy. The only handheld scanning densitometer in the industry with built-in
scanning and single-point (spot) measurement capability, it literally does the work of two densitometers.|
The 07-444 measures and stores daily film data for up to 20 different x-ray film processors for 31 days in its own built-in memory. Use it to generate and print control charts and D-Log-E curves directly to a printer without using external software and a computer. Set base-line (target) and tolerance levels for each control chart parameter either manually of automatically by scanning and averaging up to 9 different film strips.
