Portable photometer PR-524 / PR-520 LiteMate

autoranging

Features The PR-520 (PR-524 and PR-522) system combines illuminance (with PR-524 - utilizing true cosine correction) and luminance (with PR-522) measurement capabilities - unique for handheld photometers and colorimeters. 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-524 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.
