uRAD-FL-LP Radiometric - Flat Response, Low Profile Sensor

This Watt Meter System combines a low profile radiometric sensor and a flat filter / diffuser.  It provides measurement of radiant flux in units of Watts of mW.

Combined with our highly popular S471 portable photometer, the system provides simple and precise measurements.  The package includes a battery charger and necessary connector cables.

Under the UDT Instruments brand, Gamma Scientific manufactures a broad range of precision photometers, radiometers, colorimeters and photosensors for optical measurement application.
