ELECTRONICS FOR PHOTODIODES

Photocurrent Digitizer
Converts small DC currents into digital values, to display and record your measurements on your computer. Replaces expensive Picoamperemeters, no specific previous metrological knowledge needed.
- 4 selectable current measurement ranges, pA - µA
- digital values transmitted via USB to a computer
- incl. software control via PC, easy to use
- incl. PTB traceable current calibration
- portable, compact size (80x130x28 mm)
