Pros & Cons
Pros
- ✓ Backed by IMARS's warranty and support channels
Cons
- ✗ Check battery runtime and RPM/CFM specs match your case size and cleaning frequency
- ✗ Price, stock, shipping and returns are set by the retailer and may have changed since this page was last updated
SpecPicks Verdict
SpecPicks scored IMARS 3-in-1 Handheld Oscilloscope Multimeter with Signal Generator using a rating × review-volume × price-fit model applied to published specs and reviews across the tools & maintenance category. IMARS's tools & maintenance lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering. Prices and stock are set by the retailer and may have moved since this page was last updated.
Key Features
- 【3-in-1 Multifunction Integration】Combines a single-channel oscilloscope, true RMS multimeter, and signal generator (sine/square/triangle waves) in one compact device. Eliminate messy cables and device switching—perfect for basic circuit debugging, educational labs, and DIY electronics projects.
- 【12MHz Bandwidth & 50MS/s Sampling Rate】Features 12MHz bandwidth and 50MS/s sampling rate to accurately capture and display mid-to-low frequency signals. Ideal for measuring audio circuits, microcontroller digital signals, sensor outputs, and power supply waveforms with reliable clarity.
- 【Full-Feature True RMS Multimeter】Measures AC/DC voltage (up to 1000V), current (up to 10A), resistance (60MΩ), capacitance (99.99mF), frequency (1Hz-20MHz), diode test, and continuity. A versatile tool for all-purpose electrical testing and troubleshooting.
- 【Built-in Adjustable Signal Generator】Generate sine, square, and triangle waves from 100Hz to 100kHz with 10 output amplitude levels (0.1Vpp to 3Vpp). Use it to test amplifier circuits, stimulate digital systems, or verify sensor responses—no extra equipment needed.
- 【Portable & User-Friendly Design】Powered by a rechargeable 1500mAh battery with Type-C charging for cord-free operation anywhere. The 2.4" color display shows clear readings and waveforms. Great for students, hobbyists, and on-site technicians.
