Comparing the 550 and 850

Called "Universal" interfaces because they can accept both PASPORT (blue) and classic ScienceWorkshop (black) sensors directly, the 550 and 850 also boast unparalleled features and functionality.

The 550 Universal Interface is fast, flexible, and affordable, and it still has all the power you need to ignite student learning in your lab. The 550 is equipped with high-speed data collection, signal generation and power supply, FFTs, timers and more.

Unlike the 850 the 550 works with SPARKvue software and has bluetooth connectivity (as well as USB connectivity), making it the choice for use with tablets.

The 850 Universal Interface has all the speed and power you need for your most demanding physics experiments. And it can replace most of the equipment in your physics lab including oscilloscopes, power supplies, timers, and function generators, multi-meters and more.
