HEILAND ELECTRONIC TRD 2 black and white densitometer - with 3 mm measuring aperture and power supply.

A push-button allows switching between transparent and reflective mode. When the measuring lever is pressed down, the display and measuring light are switched on automatically.
When the measuring lever is pressed down, the display is set to 0.00 with another button. A separate zero point is stored for each measuring mode. The measurement is done continuously about 3 times per second, this allows to find the brightest and darkest spots. This device allows the density measurement of films and papers and is already in the basic version perfectly suitable for all typical measurements in black and white photography.

Densitometer

Precise measurement of optical density enables the exposure and development of film and paper to be quickly optimised.

Monitoring of technical processes on transparent materials is also easy, as thickness and optical density correlate. Measured values up to 6 logD (<1/1000000 transmission) can be reliably determined with special versions of our devices.

The devices from Heiland electronic usually work monochromatically in the visual range and can be individually adapted to the task.

Advantages for the user by using the densitometer:
- The quality of your negatives is considerably improved by specific corrections of exposure and development.
- Any film-developer combinations are optimised quickly and reliably.
- Material and process control also possible when enlarging.
- Fast process control for X-ray and microfilm development.
- Calibration of monochromatic inkjet printers for fine art prints.
- Precise and long-term stable measuring values due to solid metal construction.
- Low basic price due to modular system.
- Optional equipment allows adaptation to a wide range of tasks.
- Compact design
- ideal for mobile use.
