The BT-73EU voltage tester is an easy to use tool to do battery-less voltage detection. However, it features a diverse set of battery powered functions. With CAT III and CAT IV safety it can be plugged into a socket without any worries. The display can be used to accurately measure voltage. The device will power off automatically to extend battery life. The BT-73EU can detect 3-Phase rotation and give bar graph feedback on electric field strengths. With a built in leakage resistor the device can be used as a RCD.
