COM4LAB Master Unit


The COM4LAB Master Unit is a multifunctional, compact, measuring interface. As a universal base station it is used for the operation and power supply for the COM4LAB experiment boards and as an independent measuring laboratory. The Master Unit can be simultaneously connected to up to four digital terminal devices (PC, tablet or smartphone)  for the recording of measurements and for remote control of its built-in functions. The Master Unit can be quickly attached to an experiment board. Its clear and structured design results in easy operation.
