Net-PAD - External Ethernet A/D Converter

Net-PAD

Net-PAD is an external high resolution A/D converter for chromatography data acquisition. Net-PAD communicates with a PC over Ethernet through a TCP/IP protocol. Clarity Chromatography Station, configured with Net-PAD converter, enables users to acquire chromatography data from distant instruments without the necessity of installing additional cables. Net-PAD is compatible with any GC, HPLC, GPC, IC, CE system with standard analog output. The Clarity Chromatography Station can handle any combination of available DataApex converters (internal PCI, external USB and TCP/IP).
