The invention provides a multi-parameter real-time monitoring system for a tracer test and a method thereof. The multi-parameter real-time monitoring system for the tracer test includes an image acquisition device used for acquiring real-timely a tracer test field image and transmitting the image into a monitoring main machine. The monitoring main machine is in communication with a tracing instrument main machine and a flow instrument main machine. The tracer instrument main machine is connected with a tracer instrument detection head fixed on a fixing device. The multi-parameter real-time monitoring system is simple in structure, convenient to assemble and easy to operate, and can be used for achieving online real-time monitoring and real-time control of the tracer test so that test efficiency and test measurement accuracy can be greatly improved, and the test cost is lowered.
