Experimental Instruments » LEMI-1 CCD Young' s Modulus Measuring Instrument
Introduction
The measurement of Young's modulus is one of the classical assignments that frequently appear in the basic laboratory courses of general physics at colleges and universities. This instrument is a laboratory type design with microscope and CCD imaging system. It acquires length variation images of weighted sample through a microscope imaging system to determine Young.s modulus.
Key Features
Very easy to operate, simple structure and stable performance,
visual result displayed by a monitor, documentation covers both theoretical and practical descriptions.
