Radiometer / Photometer
The IL1400A combines the latest technical innovations in low level current amplification technology with microprocessor controlled simplicity. The onboard computer interrogates each "smart" detector for units, calibration
and range information, automatically displaying a calibrated reading in the correct optical units.
The operating buttons are simple and straightforward, with all essential functions under microprocessor control. In addition to being user-friendly, the IL1400A provides performance specifications unmatched by any other hand-held radiometer on the market.
