Colibrick A/D Converter

Colibrick is an external 24-bit A/D converter that measures the voltage of chromatographic and electrochemical detectors.

Colibrick is designed for analog data acquisition from any chromatograph for Clarity chromatograpy software. It uses the USB communication cable and is therefore powered directly from the computer. The unit can be connected or disconnected anytime without the necessity to switch the computer off. The input connector is compatible with the internal INT7/9 boards and U-PAD/2 devices.

Colibrick is a modernized successor to the U-PAD2 converter and the Int9 card.
