UM120 USB-Multimeter

The JT-UM120 is the digital all-round multimeter. USB ports often differ greatly in their quality and available power. With the JT-UM120, you can conveniently keep track of all measured values and also have a quick-charge trigger for mobile communication devices. The versatile display modes, such as overview measurements, detailed measurements and real-time graph view, offer a particularly wide range of analysis options.

Additional functions such as evaluation via separate PC software, automatic, orientation-controlled display rotation, cable resistance measurements round off the overall package.
