If your application specifically requires that no other forms of communication be present check out our USB Only devices. Our more advanced devices support multiple communication options, one such device is our latest product the T7, which has a Pro version that operates using USB, Ethernet, and 802.11b/g WiFi. To view our Ethernet DAQ product offerings please see our Ethernet DAQ (data acquisition) products. To view our WiFi DAQ product offerings please see our WiFi DAQ (data acquisition) products.

Please note that the term "DAQ (data acquisition)" implies products that connect to a PC to acquire data. Hence, the term "Ethernet DAQ" means that this communication occurs using a PC's active network connection. If you need an instrument that can operate independently from a computer we have Data Logging compatable DAQ devices that are capable of periodically recording to internal memory for later use.
