Owon HDS242 40 MHz Handheld Digital Multimeter

The HDS242 is a portable dual-channel oscilloscope that can also be used as a multimeter and a function generator. The meter sports a 3.5″ high-contrast colour display suitable for outdoor use and it runs on a pair of 18650 batteries, good for up to 6 hours of continuous use. You can hook up the meter to a PC host with USB-C to use it with Owon’s desktop software, control it via SCPI or to use it with a power bank.

Besides being an oscilloscope, it independently acts as a fully featured 20,000 count True-RMS multimeter. It has the capability to measure voltage, current, resistance, capacitance, continuity and diodes. The readings will be displayed comfortably large on the display.
