USB Only DAQ Options

LabJack produces low cost, high quality, multifunction data acquisition and control products capable of USB communication without the addition of Ethernet ranging in price from $130 to $410. We offer DAQ devices that only operate only using USB, a mix between USB and Ethernet, and our latest product the T7 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 "USB DAQ" means that this communication occurs using a PC's USB port. 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.

LabJack Software Options

The LJM Library is a set of functions used to easily communicate with several of our devices using a simple Modbus over USB interface (as well as Modbus TCP/UDP when applicable). The goal is to be easy to use and understand, yet flexible.
All important values and data from the device can be read and/or written by using the associated register(s).

LabJack's DAQ devices have a wide range of features

  • Analog Inputs

  • Digital I/O

  • Analog Outputs

  • PWM, Quadrature ...

  • SPI, I2C, Async Serial ...
