Cobra SMARTsense Energy - Sensor for measuring electrical current and voltage ± 15V / ± 5A (Bluetooth + USB)

Use the Cobra SMARTsense Energy to measure DC and AC voltages as well as currents of up to ± 15 V (± 5 A) and investigate the basic concepts of electricity with your pupils in a child’s play way. The sensor automatically outputs (electrical) power and energy and enables true RMS measurement of current and voltage.

With sampling rates of up to 100 kHz and a resolution of up to 1 mV (5 µA), the digital energy sensor can be used flexibly in experiments ranging from renewable energy systems to electrochemistry.

Connect the Cobra SMARTsense Energy wirelessly via Bluetooth or wired via USB to the free and award-winning measuring software measureAPP – available for iOS, Android, Windows and Linux.

Switch on. Connect. Start measuring.
