The PR-680L SpectraDuo marks the beginning of a new era in light
measurement. This unique patent pending, battery powered portable
instrument is the first and only combined fast-scanning 256
detector element spectroradiometer and PMT based photometer on the
market. The PR-680L has three available operating modes
- A fast scanning spectroradiometer (like the PR-655)
- A highly sensitive photometer (like the PR-880)
- Auto Select mode which automatically selects between detectors
based on the available signal.
The PR-680L is supplied with
4 Automated Measuring Apertures (1°, 0.5°, 0.25° and 0.125°) and an
Automated Measure Shutter. Other hardware features include
AutoSync for automatically synchronizing to the source refresh rate
insuring the utmost accuracy, a
Secure Digital (SD) port for measurement storage, an
External Trigger Port allowing remote measurement activation from either a push button
or peripheral device, and a long lasting rechargeable
Lithium-Ion (Li-Ion) battery.
