{"product_id":"plancks-constant-apparatus-plcn01","title":"Planck's Constant Apparatus - PLCN01","description":"Compact, easy-to-use apparatus. Accurate results with less than 5% error. Measures Planck's constant and estimates the work function of the cesium. The Planck’s Constant Apparatus is a compact unit containing an enclosed vacuum photocell with an attachment for illuminating light sources, a high stability power supply for applying a variable stopping voltage to the cell and a nanoammeter for measuring the resulting photocurrents.\u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e Measures planck's constant and estimates the work function of the cesium.
