MESR-100 V2 ESR & Capacitance Meter - Professional In-Circuit Capacitor Tester, 100kHz, 0.001-100 Ohm

Fixing electronics? The MESR-100 V2 is a pro tool for testing capacitors right on the circuit board! It measures Equivalent Series Resistance (ESR) from 0.001 to 100.0 Ohms using a true 100kHz sine wave, just like manufacturers do. It also checks capacitance down to 1uF. It's auto-ranging and has a fast refresh time. The best part? It applies very low voltage (less than 15mV) so it's safe for in-circuit testing without damaging other components. Great for troubleshooting TVs, LCD monitors, audio boards, and power supplies. It runs on 5V micro USB or 2 AA batteries (not included), and comes with test clips and a manual. A must-have for any serious repair hobbyist or technician.
