Product Introduction: 
Analog circuit experiment box make all the experiment module concentrated distributed on the circuit board, lead out the down-lead through the locking type jack, student can set up circuit by themselves according to experiment project, it can cultivate the ability of thought and start work, it also enhance the applicability of this experiment box. Analog circuit experiment box is based on the teaching experiment of  " higher technical school fundamentals of electronic technology  basic requirements of the course teaching" including all the experiment content of " basis of analogue electronic technique" it is the last type experiment machine for the electronic technique, electronic circuit and other course of institutions of higher education, secondary specialized school and TVET university.  

Experiment box content
