Our DSO-LCR500 combines the advantages of a digital oscilloscope and a multifunctional component tester in a compact and high-quality case. With the help of the digital oscilloscope, ambitious tinkerers can evaluate time-dependent signals without having to resort to expensive measurement technology.

The multifunctional component tester also allows fast and automatic detection of components. Furthermore, our DSO-LCR500 has additional helpful functions such as a signal generator, an infrared signal decoder and measurement of Zener diodes, DS18B20 sensors and DHT11 sensors.

The device is equipped with a 1500 mAh rechargeable battery, which can be conveniently charged via USB-C. The integrated, fold-out stand additionally eases the operation.
