Heiland Densitometer


Special order: 3 week lead time.

The best densitometer on the market today.

Densitometers are used in film photography to measure densities of negatives and the saturation of prints. Such measurements enable the photographer to choose the right photo paper and the correct exposure right away, allowing them to eliminate test strips. Once the paper and darkroom are calibrated, the first print from a previously measured negative is immediately a success.

The exposure and development of film and paper can quickly be optimized, by means of precise measurement of the optical density.

The quality of your negatives will be greatly improved by targeted corrections of exposure and development. Any film-developer combination will be optimized, quickly and safely.


Optional device configuration, allows adjustment for a large variety of tasks.
Compact design, also ideal for mobile use.
Quick process control for development of X-ray film and microfilm.
Calibration of monochromatic inkjet printers, for Fine Art prints.
Precise, long-term and stable measurements, due to solid metal construction.
Measurements up to 6 logD (<1/1000000 transmittance) can be reliably determined with special models of our devices.
Devices by Heiland electronic usually work monochromatically within the visual spectrum, and can be individually adjusted according to their task.

Type TRD 2:

Enables easy and fast tests in all photographic processes.
Measurement of logarithmic density for B&W films and papers.
A button is used to select the transmission or reflection mode.
For both transmission and reflection modes, an individual reference point is set.
Measurements are done about 3 times in one second, ensuring a continuous reading of even high densities.

Type TRD Z:

This instrument is very valuable while calibrating papers and films according to the zone system.
Acts as an electronic zone ruler, replacing estimation with measurement.
Any logarithmic density value is assigned to the appropriate zone range, which eases the interpretation of the density measurement.

Additional options for TRD 2 & Z:

- Exchangeable apertures
- USB port
- Measurement range extended to 5.5 logD
- Extended display resolution (0.001 logD)
- Measurement range is extended to 6.5 logD
- Multi-color LED (creates red, blue, green or white transmission light)
