Model DI-158 vs. DI-155
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-158 is discontinued and replaced by model DI-155. The DI-158 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 and DI-149, the DI-155 employs virtually indestructible analog and digital inputs, and adds counter/time capability. The following table summarizes the major differences between the DI-158 and its replacement, the new DI-155. Refer to the DI-155 Data Sheet for more details.
