UNI-T UTD1025CL Handheld Oscilloscope
The UNI-T UTD1025CL is a handheld digital storage oscilloscope that integrates single-channel waveform capture with multimeter capabilities in a compact, battery-powered unit. Equipped with a 25 MHz analog bandwidth and 200 MS/s sampling rate, it handles a variety of common signals both in lab and field settings. Its ergonomic front panel features a one-button Auto Setup that automatically adjusts vertical scale, timebase, and trigger for a stable display upon signal connection, streamlining measurements for rapid diagnostics.
The 3.5″ high-contrast TFT LCD ensures clear visibility even in bright environments. Isolated USB connectivity allows safe data transfer to PC and firmware updates. Memory depth supports waveform recording and recall, while 22 auto-measurement types accelerate analysis of parameters such as amplitude, frequency, and rise/fall times. Built-in multimeter functions (voltage, current up to 6 A via UT-M07 module, resistance, capacitance, diode, continuity) eliminate the need for separate instruments.
Modes like Peak Detect capture narrow or transient pulses, and AVG smoothing reduces noise. FFT operation on the single channel provides frequency-domain insight. With up to 8 hours of battery life, multilingual help, and straightforward Printscreen, the UTD1025CL is designed for ease of use, reliable performance, and versatile electronic troubleshooting in educational, maintenance, and portable diagnostic scenarios.
