Calibrated Reference Sensitometer and Scanning Densitometer
The darkscan duo ref is a high-precision combination of reference sensitometer and scanning densitometer in one unit.
It is designed for acceptance testing as well as daily routine testing of x-ray film-screen equipment according to IEC 61223-2-1, DIN V 6868-55, and DIN 6868-2 standards.
The device combination provides functional and technical advantages such as one power supply (batteries or rechargeable batteries), less maintenance cost, and less room for operation or storage.
The sensitometer section is suitable for blue and green x-ray films. The exposition for blue and green films is manually adjustable in 5 steps. The step wedge with 21 steps has an optical step wedge constant of 0.15. The exposition homogeneity of each step is almost constant. The maximum tolerance is ± 0.01 log (H).
