Device to measure Planck's constant

  1. Dec 8, 2013 #1
    Hi people,

    I was wondering if anyone knows of any commercial device to measure directly Planck's constant. I mean no use of indirect measurements, just to press a button and for the number to appear in a screen.

    Thanks

    I do not mean that obviously. I have a reason to measure the Planck's constant, but I indent to do the minimum number of indirect measurements most devices need.

    I know of no way that Planck constant can be measured directly.In fact I think that is not possible.
    But about measuring Planck constant by just pushing a button,maybe someone makes a device which does the photoelectric experiment and does the calculations itself!!!!!!

    Thanks anyway. Can somebody indicate me a good device to measure it by doing the photoelectric experiment, being quite precise, but not that much expensive? I know I may be asking too much

    Try That Paper.
