Net-PAD - External Ethernet A/D Converter

August 2014: Net-PAD has been discontinued from production.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 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 Station can handle any combination of available DataApex converters (internal PCI, external USB, and TCP/IP).
