DI-145 Starter Kit DAQ
This data logger is manufactured in the United States of America


The DI-145 is a new product in a long line of low-cost starter kits from DATAQ Instruments. Suitable for measuring preamplified analog signals, the DI-145 in tandem with the included WinDaq software allows real time data acquisition, playback, and analysis performance equal to or better than other products that cost ten times or more than its low price. Predecessors of this instrument have been sold to over 20,000 hobbyists and professionals for countless data acquisition applications around the world. The DI-145 continues this legacy with an improved interface, and noise-cancelling differential analog inputs that are transient-protected to ±150 VDC or peak AC. This is our toughest and most tolerant starter kit ever.

The DI-145 offers four analog input and two discrete (digital) input channels. The analog inputs offer a fixed measurement range of ±10VFS, and are multiplexed to an integrated 10-bit ADC. Both analog and digital inputs are protected to ±150 and ±30 VDC or peak AC respectively. Sample rates as slow as 2.23 per min. and as fast as 240 per sec. (divided by the number of enabled channels) are supported. Included WinDaq software allows a real time display of any combination of analog channels, and the ability to stream acquired data to disk in recorder-like fashion. The DI-145’s two digital inputs are dedicated for remote stop/start and remote event operations using WinDaq software. WinDaq also includes software to review recorded data files, including waveform analysis and data file export to Microsoft Excel and other applications.
