Photo Transistor Characteristics App with Two Analog Meters

This instrument is used to plot a graph of Current versus Intensity of Light at different values of applied voltages. Power Supply: Built in IC regulated power supply 0-15V continuously variable. Two round analog meters - one meter for voltage measurement & another meter for current measurement, are fitted on the panel. Photo Transistor is mounted separately on the plastic box properly wired for convenient experimental use.
Rest specifications are same as per Cat. No. 2015.
