FNIRSI DST-210 Handheld Oscilloscope Multimeter 48MS/s 2.8″ Display

Description

Product Overview

The FNIRSI DST-210 is engineered as a versatile 2‑in‑1 testing instrument, merging a 48MS/s digital oscilloscope with a full‑featured digital multimeter in a single handheld unit. Its 2.8″ TFT color display presents waveforms with clear contrast, while a 10 MHz bandwidth ensures accurate capture of low‑frequency signals. Powered by a 3000 mAh rechargeable battery, the device operates up to 15 hours on a single charge, making it ideal for on‑site diagnostics. Dimensions of 7.5 × 3.5 × 7.5 inches and a weight of 1 lb provide true portability without sacrificing performance.

Usage

Designed for electronics technicians, hobbyists, educators and R&D engineers, the DST‑210 excels in laboratory benches, field service calls, classroom labs and maker spaces. Use the oscilloscope mode to visualize signal integrity, troubleshoot circuit timing, or verify sensor outputs. Switch to multimeter mode for precise voltage, current, resistance and continuity checks. The built‑in 13‑waveform signal generator (0‑10 kHz) supports circuit testing and calibration without external equipment.
