U-PAD2 - External USB A/D Converter

U-PAD2 - External USB A/D Converter

Discontinued from sale as of January 2013.

U-PAD2 is an external 24-bit A/D converter that measures the voltages of chromatographic and electrochemical detectors. Integration frequency up to 400 Hz enables Fast GC application.

U-PAD2 uses the USB communication channel and thus is directly powered from the PC. The unit can be connected or disconnected anytime without the necessity to switch the computer off. The input connector is compatible with the internal INT7 board.
