China Wholesale Magnetization Curve Pricelist – LEEM-10A Experimental Apparatus of PN Junction Characteristics – Labor

Short Description:

LMEC-21 uses steel string and oscilloscope to measure the standing wave and vibration of uniform string, and can expand innovative experiments, this instrument needs self-prepared oscilloscope.
LMEC-21A is a cheaper version which don't need oscilloscope, The purpose of the instrument is to set up interesting string sound experiments. It can not only do the traditional basic string vibration experiment, but also expand to the applied experiment to calibrate the intonation of string instruments and learn the working principle of string instruments.
