ESR70 Atlas ESR+ Capacitor Tester – 0.00–40Ω ESR, 1µF–22,000µF Capacitance

The ESR70 Atlas ESR+ is a professional ESR and capacitance meter designed to evaluate electrolytic capacitors both in-circuit and out-of-circuit. This model is a valuable tool for technicians, repair engineers, and electronics hobbyists, offering quick and accurate measurements of Equivalent Series Resistance (ESR) and capacitance without requiring component removal.

Featuring automatic analysis start, polarity-free test leads, and clear audible alerts based on the condition of the capacitor, this compact tester streamlines the troubleshooting process. It includes automatic capacitor discharge protection and an intuitive interface, all powered by a single AAA battery.

Perfect for identifying faulty or degraded capacitors in LCD TVs, power supplies, and other consumer electronics, the ESR70 Plus provides a balance of ease of use, reliability, and affordability.

Key Features:

• Accurate ESR Measurement: Measures ESR from 0.00Ω to 40.0Ω with resolution as fine as 0.01Ω for low ESR values.
• Capacitance Range: Supports capacitance testing from 1µF to 22,000µF, ideal for most common electrolytic capacitors.
• In-Circuit Testing: Tests ESR while the capacitor is still soldered to the PCB, saving time during repairs.
• Automatic Discharge Function: Safely discharges capacitors up to ±50V before each test.
• Intelligent Audible Alerts: Distinct tones indicate ESR range for fast assessment without needing to read the display.
• Polarity-Free Probes: Connect either way around—no need to worry about polarity during tests.
