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 / Palladium printing
Kallitypes, Van Dyke browns
Solarplate™, ImagOn™ or similar photopolymer and photogravure processes
and similar processes which use UV light to expose an image
We offer two versions of meter, both designed to enable the artist to get perfect exposures every time. The PPM-2 is more suited for manual exposure work, while the PPM-3 is intended primarily for studio work and offers features such as audible alarms and the ability to switch external equipment.
Using one of our meters will allow you to get perfect exposures, 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. Initially 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 - you only need do this one time. You 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.
Examples of our meters in use by our customers:
Please note that several of these images show the PPM-1 meter which is no longer offered. The PPM-1 was very similar to the PPM-2 except that its sensor was internally mounted. The sensor and operation of the PPM-1 are otherwise identical to the PPM-2 and everything shown here with a PPM-1 can be done using a PPM-2 or PPM-3.
