PR-525Modern Technology

The PR-525 colourMate brings hand-held, colourimetric measurements into the 21st century. It features a backlit touch- screen LCD display, USB interface, MMC (or SD) card slot and rechargeable lithiumion battery. Measuring refreshing sources? The PR-525 automatically syncs to non-DC signals. The PR-525 can be triggered remotely, and once triggered, will send a pulse to a remote device such as a xenon strobe. This way, single event sources can be measured.

Ease of Use

All set-up parameters, data display and management is handled by “touching” through menus on the on board display. Making a measurement is as easy as pressing the only button on the PR-525 - the measurement button.

16 Heads are Better Than One

If you have a need to make simultaneous colour measurements of multiple areas, say uniformity of a projected image,the PR-525 can be outfitted with up to 16 remote heads (PR-515 Remote Head) all individually addressed and controlled from a PC talking to the PR-515 base unit using the included PR-525 software.

Data Transfer

Following measurements, data can be sent to a PC via the USB interface - or the multi-media storage medium (MMC or SD) can be removed and inserted into a card reader connected to a PC..
