Our Review
The COHEALI Digital Multimeter delivers solid baseline functionality for homeowners tackling basic electrical diagnostics. The large backlit LCD screen is genuinely readable in poor lighting, and auto-ranging eliminates manual scale selection—a convenience that reduces user error. Build quality feels adequate with a standard plastic housing; it's lighter than professional-grade meters but acceptable for occasional use. Battery life is respectable at roughly 40 hours of continuous operation on standard AAA cells. However, the meter lacks true RMS voltage measurement and shows noticeable calibration drift after 6-8 months of storage, requiring recalibration. For diagnosing dead outlets, tripped breakers, or basic continuity checks, it's competent. Durability is modest—the test leads feel thin and prone to cracking with rough site use.
What We Like
- Large, clearly lit LCD screen with strong contrast makes readings easy even in dim basements or attics
- Automatic ranging saves time and prevents accidental component damage from scale selection errors
- Compact and lightweight design with included carrying pouch—genuinely portable for moving between rooms
Watch Out For
- Lacks true RMS mode, limiting accuracy on variable AC loads common in modern switching power supplies
- Test lead quality is substandard; the probes are flimsy and connectors loosen after extended field use
The Verdict
“A capable entry-level multimeter for homeowners who need periodic electrical checks but shouldn't be trusted for critical troubleshooting without verification testing.”
