Photovolt Reflectance Meter 68-04-00 (Model 577) The Photovolt is designed to simplify the determination of appearance characteristics. This rugged portable instrument is easy to operate, sets up in just minutes and provides you with unparalleled flexibility. Now available with serial data port option. You can read percent reflectance directly from a sample by using any one of Photovolt’s standard “search unit” packages. With the Photovolt it becomes easy to measure color, opacity, hiding power, brightness and tristimulus reflectance. With just the touch of a button the Photovolt will automatically reconfigure itself for changes in search unit filters. Naturally, the Photovolt has applications that conform to ASTM, TAPPI, and ISO standards. NEW! Serial data port option sends the current reading to your PC with a touch of a button on the side of the search unit. The included PortKey™ software takes the reading and inserts it in ANY Microsoft Windows™ program as though it was typed in from the keyboard. No programming is needed and it works with all Windows programs including spreadsheets and word processors. Other features include easy-to-read LED display with a handy “hold” function, durable solid state construction and a calibration reflectance memory for up to three tristimulus or colored glass filters.
