Using a light source aimed at a photoelectric cell, the Heiland TRD-2 Densitometer is able to determine the optical density of any given photographic material, eliminating the need to make test strips.
- Quick process control for developingt of x-ray film and microfilm
- Optional device configuration, allows adjustment for a large variety of tasks
- Measurements up to 6 logD (<1/1000000 transmittance) can be reliably determined with special models
- Devices by Heiland Electronic usually work monochromatically within the visual spectrum, and can be individually adjusted according to their task
