Featured Equipment

Sound Sensor with Microphone

The Sound Sensor houses a sensitive microphone designed to display audio waveforms of sound levels between 45 and 100 dB.

Resonance Boxes: Sympathetic Resonance Box Set

These boxes are constructed from hardwood and feature an C4 tuning fork mounted directly to the box. If tuned to the same frequency, striking one will cause the other to go into sympathetic vibration.

Support

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.
