Analog DC Microammeter, 0-500µA (10µA Resolution) Subcategory_Rulers and Measuring supporting up to three pendulums

supporting up to three pendulums simultaneously for harmonic-motion work

Combining filtration and titration on one base

Proves horizontal velocity does not affect vertical fall time through a push-button launcher that simultaneously projects one steel ball and releases another

sized for ripple tank and bulb-driven physics demonstrations

Analog DC Microammeter, 0-500µA (10µA Resolution) Subcategory_Rulers and Measuring supporting up to three pendulumsFive hundred microamp analog DC microammeter at 10uA resolution, sized for the next step up from the 100uA meter when small signal circuits exceed its full scale deflection.
