Net-PAD - External Ethernet A/D Converter
Net-PAD is an external 24-bit A/D converter communicating with a PC over Ethernet through a TCP/IP protocol.
Discontinued from sale as of August 2014.
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 Software, configured with Net-PAD converter, enables users to acquire chromatography data from remote instruments without the necessity of installing additional cables. Net-PAD is compatible with any GC, HPLC, GPC, IC, CE system with a standard analog output. The Clarity Chromatography software can handle any combination of DataApex A/D converters.
