LabJack U3-HV

USB DAQ device with 4 dedicated ±10V, 12-bit  analog inputs, 12 flexible I/O, and 4 dedicated digital I/O. The flexible I/O can be configured as either digital or analog, thus providing up to 16 analog inputs, or up to 16 digital I/O. It also has two 10-bit analog outputs, up to 2 counters, and up to 2 timers.

USB Multifunction DAQ

The U3 family devices are versatile for measurement and control within simple analog and digital systems. With the option to configure I/O as either analog or digital, you have flexibility when choosing sensors for your application. Common applications include hobbyist projects, educational programs, industrial control and monitoring, and prototype development.

U3-HV ±10 volts or -10/+20 volts

U3-LV (Low Voltage) 0-2.4v and/or 0-3.6volts

USB Only Customers needing 16+-bit Analog Inputs should consider the Labjack T7 and customers needing Ethernet or onboard scripting abilities should consider our T-Series devices.

We Recommend the T4:

We recommend the T4 over the U3. The T4 is a newer, significantly more capable device. Key improvements include:

• Faster Processor: Delivers faster execution speeds and reduced response latency and higher maximum sampling rates.
• Modern Driver & API: Features a newer, easier-to-use, cross-platform driver and API architecture.
• Onboard Scripting: Runs standalone code directly on the hardware without requiring a host PC.
