Hand-Held Dual-Color Sensitometer
Now it's easy to make high-quality control test films. This unit has variable exposure time settings for blue and green-sensitive film. Just raise the platen, insert film, lower platen, push a button, and exposure is made. Features a 21 step density wedge with numbered 0.15D increments.
Light Source: Dual-color electro luminescent. Blue 455nm ± 10nm; green 520nm ± 10nm. Repeatability: ± 0.04D log exposure from unit to unit. Stability: ± 0.02D log exposure per year at 10°C - 45°C. Exposure Area: 21 steps, each 5mm x 10mm. Tablet Densities: 0.05 to 3.05D in 0.15D increments. Exposure Time: Adjustable, 50-500 ms typical. Exposure Adjustment: Separate screwdriver adjustments = 0.5D on each color. Controls: 1. Push-to-expose button with buzzer monitor and 2-second delay to prevent double exposures. 2. Blue/Green switch. 3. Power switch - none required. Unit draws no power on stand-by. Power: Size: Two 9V alkaline transistor batteries. Weight: MN1604 or equivalent. Optional AC power converter. 7-5/8" L x 5-1/4" W x 3-5/8" H.
