About This Product

Students hang known masses from the spring, read the extension against the mirror-backed scale and plot load against extension to find the spring constant k and check Hooke’s law. Educational Instrument can dispatch the K Constant Spring Apparatus to laboratories in Costa Rica, Montenegro, Sierra Leone, Madagascar, Malta and Paraguay.

Frequently Asked Questions

What is the mirror on the scale for?

The mirror backing lets students line up the pointer with its reflection, which avoids parallax error when reading the 1mm graduations.
