Light Meter/Spot Meter PR-520 NO LOMGER AVAILABLE
The PR-520 system combines illuminance (utilizing true cosine correction) and luminance measurement capabilities - unique for handheld photometers and colorimeters. This meter also provides an attachable Pritchard optics lens for measuring spots focused in the lens.
To make Continuous Measurements, simply press and hold the measurement button. Results are displayed instantaneously - no detector integration or dark measurements to wait for.
A special Peak/Valley data locking feature lets you display the largest (Peak) or smallest (Valley) value during a continuous measurement sequence.
Use the Delta capability to automatically calculate the photometric differences between two samples.
Back Lit Touch Screen Display
All instrument set-up, measurement setup and file operations are performed via menus on the touch screen display. The built-in back light makes it convenient for working in dark ambient environments.
Multiple Measuring Heads
If your application requires a multi-spot measurement such as projector uniformity, the PR-520 can be fitted with up to 9 remote measuring heads - all under the control of a PC communicating with the base unit over the USB interface. Each remote detector is individually addressed.
AutoSync ® Source Rate Synchronization
Accurate measurements of pulsing or repetitive sources is assured with the SYNC feature of the PR-520. The instruments can be instructed to automatically detect the rate ( 20 to 400 Hz ) of the sample and adjust the measurement acquisition accordingly. You can also enter the frequency value manually.
When it is necessary to either perform a hands off measurement or to measure a flashing source such as a camera flash, the PR-524 can be triggered remotely, and once triggered, will send a pulse to the remote source. Or, it can be used simply as a remote trigger.
Instruments can be controlled from a PC using the Remote Mode command language by sending and receiving ASCII text instructions over a virtual COM port - standard equipment with the PR-520.
A rechargeable Li-ion battery means portability - up to 12 hours on a single charge.
A built-in USB Interface lets you connect to the outside world.
Save thousands of measurements on the Secure Digital (SD) card.
PhotoWin 2 Windows software can be used to control the PR-520 systems to provide a powerful and easy to use graphical user interface (GUI) for:
