Featured Equipment

Banana Plug Cord-Red (5 Pack)

These heavy, insulated patch cords are convenient, durable and inexpensive. The grips are stackable and made of soft plastic for flexible strain relief. The spring connectors rotate in the grips, reducing wear due to friction. Length of 75 cm, set of 5.

Right Angle Clamp

This clamp fits rods up to 18 mm (11/16 in) in diameter.

Student Power Supply

Student Power Supply, 18VDC, 3A

This high quality, compact power supply provides the DC voltage and current levels necessary for most introductory student labs.

Four-Scale Meter Stick

Four Scale Meter Stick

A convenient measuring device that includes four different metric scales of various precision.

3-Axis Magnetic Field Sensor

Wireless Magnetic Field Sensor

This 3-Axis Magnetic Field Sensor can sense the Earth’s magnetic field, magnetic fields from current-carrying coils, and permanent magnets.

Aluminum Table Clamp

This clamp with 6.5 cm grip width, accepts plain or threaded rods up to 1/2 inch or 1.25 cm.

45 cm Stainless Steel Rod

45 cm Stainless Steel Rod

Non-threaded and non-magnetic lab rod.

AC/DC Electronics Laboratory

AC/DC Electronics Laboratory

Facilitates electricity experiments for AC and DC. Can be used as a stand-alone with a multimeter or with PASCO sensors and software.

Magnet Wire (22 Gauge)

Magnet wire used for crafting a coil used as an electromagnet.

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.
