  • Optimise exposure settings for highlight, shadow areas and mid-tones
  • Wide sensitivity range - exposures from 1/2000s to > 1 hour
  • Settable film speed
  • Two memories - store shadow or highlight tones while metering another to optimise exposure across the image
  • Convenient hand-held battery-operated meter unit, intuitive and easy to use

Future Products - the "Darkroom Assistant" Range

The "Darkroom Assistant" is being developed for the darkroom user.

These products are being developed with the needs of the darkroom user as a highest priority. The products feature ergonomic design for use in the dark and low-light conditions:

  • Tactile switches
  • IIlluminated displays and controls in “safe” red
  • Ultra-dim display mode when using sensitive panchromatic materials
  • High-contrast, high-legibility fascia marking

 Temperature-Compensating Developing Timer

As with many chemical processes, the development of photographic materials is very temperature dependent, with development times shortened at higher temperatures and lengthened at lower temperatures.

The compensating timer takes the hit-and-miss out of developing. The timer runs at a rate dictated by the temperature of the developer solution so that you can be sure of always getting the results you need - independent of the ambient temperature conditions.

Temperature is measured continually during the development process and the timer run rate adjusted automatically so that the correct timings are acheived even as the temperature changes during the development process.

The temperature compensating timer features:

  • Temperature compensation "on" (compensated) or "off" (timer runs at real time)
  • Implements the standard "Ilford" compensation curves.
  • Accurate - using a precision temperature sensor, 10-bit A-D conversion and digital timing
  • zero to one hour timing range, resolution one second.
  • Bench-top use or wall-mount
  • Battery and mains power
  • Clamp for developing tray use - included
  • Gland for sealing sensor into tank - included
