Find failing capacitors faster and troubleshoot electronics with greater confidence using the ESR meter designed for practical bench and repair work. The MESR-100 is an auto-ranging capacitor tester that measures ESR and low resistance from 0.001 to 100Ω. Its true 100kHz sine-wave testing helps deliver reliable ESR measurements, while in-circuit testing can reduce unnecessary component removal during initial diagnostics. A clear 128×64 LCD, one-key zeroing, and automatic range selection make everyday testing straightforward for technicians, repair professionals, and electronics enthusiasts.
Key Features
- True 100kHz sine-wave ESR measurement with resolution down to 0.001Ω.
- In-circuit ESR tester functionality helps diagnose capacitors directly on compatible circuits.
- Auto-ranging selects the appropriate measurement range, with manual 1Ω, 10Ω, and 100Ω ranges available.
- Built-in 25V electrolytic capacitor reference table helps you quickly assess capacitor condition.
