Atlas ESR70 Capacitance and ESR Meter

ESR Resolution as fine as 0.01 ohms
Audible alerts for various ESR levels
PEAK Atlas ESR70 (ESR PLUS) (Equivalent Series Resistance) Capacitor Analyzer with audible alerts. This new model introduces new features including "Audible Alerts" and enhanced measurement range. Every measurement of ESR will be shown on the display as usual of course, but the unit will also produce a variety of tones depending on the value of ESR. And the tones themselves are surprising pleasant, including "Bell-like" pings (a couple of different types for ESR that is below certain values), and also a "Beep-Barp" type tone for ESR that is likely to be too high.

There is also a reassuring "Blip" when the measurement has started and completed. The ESR measurement range has also been enhanced, now doubled, measuring from 0 to 40 ohms with a resolution as low as 0.01 ohms. This remarkably fine resolution is great for assessing large capacitors and even allows you to use the Atlas ESR+ for tracing short-circuits and finding the precise area of a PCB that has that invisible wisp of solder. Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. The Atlas ESR70 PLUS offers instant results, if the instrument is switched on then just connect the probes to your capacitor and the analysis starts automatically.

You can even use the Atlas ESR70 PLUS in-circuit, saving you the trouble of removing capacitors. When testing capacitors out-of-circuit, the unit will also display the capacitance.
