The JOY-iT DMSO2D72 is your ideal companion for the workshop and outdoor use. It combines a 2-channel oscilloscope, a signal generator for any wave type as well as a multimeter with 6 different measurement types in one device and serves all functions you expect from individual devices.
JOY-iT has placed particular emphasis on simple, clear and practical handling in order to make work as pleasant as possible for the user. For this the DMSOD72 is equipped with a 'one-button' auto measuring function and a 'one-button' page out. In addition, 2 signals can be compared directly on the 2.8' 65K colour LCD display. The power supply is provided by two 18650 lithium batteries, which are included in the scope of supply and allow a continuous operation of one day as well as a standby time of up to 8 weeks. Furthermore, operation via the USB-C interface is also possible, during which the batteries are charged simultaneously.
In order to protect the device perfectly in 'outdoor use', the DMSO2D72 was equipped with a silicone sheath, which offers protection against shocks, dirt and heat. The extensive and very user-friendly software is available in English, German and French and can be switched easily on the device.
You will also be impressed by the PC software, which provides you with a multitude of functions with very high ease of use.
