LightMeasure UV Exposure Meters

We offer ultra-violet (UV) exposure dose meters (also called 'integrators') designed specifically for artists who work with UV sensitive media such as:

  • Platinum or Palladium printing
  • Cyanotypes
  • Kallitypes
  • Van Dyke browns
  • Carbon prints
  • Solarplate™, ImagOn™ or similar photopolymer and photogravure processes
  • and similar processes which use UV light to expose an image

The meters are designed to enable the artist to get perfect exposures every time without the need to make test strips for every exposure, even when using light sources (such as the sun) where the UV levels might be variable.

You use the meter to establish a 'target UV dose' for your combination of light source and medium (using test strips in the usual manner) but which you only need to do one time. Then use this 'target dose' for future prints - you don't need to make any more test strips, simply use the meter to monitor the UV during the exposure step and stop when you reach the target dose.

We encourage you to read our Frequent Questions page for information about measuring different light sources or using different media.

Please see the PRODUCTS page for full details and specifications.

             The PPM-2 UV exposure dose meter with external UV sensor

             The PPM-2 UV exposure dose meter with external UV sensor

All versions have a similar control unit with a large, easy-to-read display showing the exposure data, a UV sensor, a start-stop button and an on-off switch. The main differences between the options are the sensitivity range of the sensor and whether the sensor is mounted internally or externally
