Model DI-148 vs. DI-149
Low Cost Data Acquisition Starter Kit Product Comparison

Beginning immediately DATAQ Instruments has extended the retooling of its data acquisition starter kit line up. Model DI-148U is discontinued and replaced by model DI-149. The DI-148U has been a workhorse product for nearly a decade, but advances in technology now allow us to offer more power for nearly the same low price. Extending the success of the recently introduced DI-145, the DI-149 employs virtually indestructible analog and digital inputs, and adds counter/time capability. The following table summarizes the major differences between the DI-148 and its replacement, the new DI-149. Refer to the DI-149 Data Sheet for more details.
