MESR-100 ESR Meter Auto-ranging Capacitor Tester 0.001-100Ω

Professional MESR-100 auto-ranging ESR and low ohm meter with a 0.001-100.0Ω measuring range.It adopts a true 100kHz sine wave to deliver accurate ESR measurements aligned with capacitor manufacturers' standards, and supports safe in-circuit testing with a low test voltage (<40mV RMS) that won't activate circuit semiconductors.Ideal for repairing TVs, LCDs, audio boards, and general electronic maintenance.Features include 0.001Ω high resolution, a manual zero function to eliminate lead resistance, a built-in 25V electrolytic capacitor ESR reference table, power by 2xAA batteries ( not include), and an ergonomic portable design with a 60° desktop stand.

• Dual Range Flexibility：Supports auto/manual range switching (0.001-100.0Ω) with 1% accuracy, adapting to different component testing needs.
• 100kHz Sine Wave Precision：Delivers reliable ESR readings consistent with manufacturer standards, avoiding inaccuracies from pulse-based testing methods.
• Safe In-Circuit Testing：Low test voltage (<40mV RMS) allows direct testing on live circuit boards without removing components or activating semiconductors.
• High Precision Tools：0.001Ω resolution, manual zero function, and built-in ESR reference table for quick, accurate capacitor health assessment.
• Convenient Power & Design：Power supply (2xAA batteries not include) and an ergonomic curved case with a 60° stand for handheld or desktop use.
