Smart Gate

Wireless Smart Gate

The Wireless Smart Gate has all the features of the wired Smart Gate plus the added flexibility of wireless connection to your data collection system.

Smart Gate

Smart Gate

Photogate that can be connected to any PASPORT interface, has auxiliary port to daisy chain gates, double beams for accurate speed measurement, and a special photogate tape slot.

Mass and Hanger Set

Mass and Hanger Set

The Mass and Hanger Set includes 4 hangers and 27 weights that range from 0.5 g to 100 g.

Photogate/Pulley System

Photogate & Pulley System

Measure the motion of a pulley system using this combination photogate and low-friction pulley. For use with PASPORT and ScienceWorkshop Interfaces.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
