USB Only DAQ

LabJack produces low cost, high quality, multifunction data acquisition (DAQ) and control products without the addition of Ethernet or WiFi connectivity options. These devices are typically lower in cost and have fewer points of failure for applications that are in harsh environments.

If your application doesn't require the use of USB only devices, check out our other USB DAQ (data acquisition) products. 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 compatible DAQ devices that are capable of periodically recording to internal memory for later use.
