The OWON handheld oscilloscopes are actually polyscopes or 2-in-1 instruments, since they have an oscilloscope and a multimeter incorporated in the same equipment. As oscilloscope we have available a bandwidth of 20 or 60 MHz with a sampling capacity of 500MS / s and a color screen of 3.7 ". While as a multimeter we have a 4 3/4 digit instrument (max 4000 accounts) With capacity to measure voltage, current, resistance, continuity, capacitor measurement and diode test, they are also equipped with USB port, have memory, and the inputs between oscilloscope and multimeter are isolated for greater security. -Po that gives them an autonomy of 6 hours in the field. In addition to all this commented what also makes them really attractive is its quality / price ratio. See equipment: 20Mhz HDS1021M-N 60Mhz HDS2061M-N
