ATTEN AT-H551C Handheld Oscilloscope

AT-H551C is unique all-in-one multifunction test instrument comprise of 50MHz Single Channel Oscilloscope, 6600 count high precision Digital Multimeter, Function Generator, 60MΩ LCR Meter and Frequency counter. It has a large 3.8”, 320 x 240 pixels LCD High Density Back-Lit Graphical display. Convenient and agile auto measure functions, with all measurement parameters adjustable.

In multimeter mode, both alternative current and voltage can be tested with one single probe input. No need to change probes. One single key-press can directly show the waveform of the signal. Capacitance measurement range up to 66000µF, and the measurement takes only a few seconds. Function signal output available, ranging from 10Hz to 156kHz. Real-time waveform is displayed simultaneously. Inter turn short-circuit test available. High frequency test designed for small inductance.

It’s a compact and hand held size with re-chargeable battery makes it your ideal companion for the ideal for on-field operation. Measuring and testing just became easier and more affordable than ever.
