The Wireless Current Sensor facilitates introductory and advanced explorations of the fundamental concepts of electricity and basic circuits.
Easily record voltage data while exploring fundamental circuit concepts, electrochemical batteries, and so much more.
Facilitates electricity experiments for AC and DC. Can be used as a stand-alone with a multimeter or with PASCO sensors and software.
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.
