Featuring an enhanced 0.01 ohm ESR resolution and a doubled measurement range up to 40 ohms, it delivers accurate in-circuit testing without capacitor removal. Its smart audible alerts provide real-time feedback, while automatic discharge safeguards users from charged capacitors. Compact and battery-powered, the ESR70 is the ultimate tool for diagnosing capacitor health quickly and confidently. ## Description 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, but the unit will also produce a variety of tones depending on the value of ESR. , including Bell-like pings for nominal ESR values and 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 ESR70 for tracing short-circuits and finding the precise area of a PCB that has that invisible wisp of solder. Great Service Aid Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. The Atlas ESR70 offers instant results, just connect the probes and press test. You can even use the Atlas ESR70 in-circuit, saving you the trouble of removing capacitors. When testing capacitors out-of-circuit, the unit will also display the capacitance to 0.2uF resolution. ESR can be a tricky thing to measure, which is a shame, it's a very useful diagnostic parameter. Of course, ESR meters are available from various sources, some are very famous in the repair sector, but the Atlas ESR70 is more than just another ESR meter. For a start, it's smart, both in looks and in brain. It can measure and compensate for the effects of measuring in-circuit, it also knows that you don't want to be hassled with capacitor polarity. This unit is designed with the real world in mind. Some capacitors can be charged up, a lot, but the Atlas ESR70 doesn't mind. If your capacitor is charged, the unit will automatically carry out a controlled discharge procedure before measuring the capacitance and ESR.

The leads on the unit are about 20" long anyway. **Q: I work on old Amps, can it test 350 volt & 450 volt capacitors.this question is pertaining to the Atlas ESR 70** A: As others have mentioned, it can test those capacitors if they are in their discharged state.The manufacturers specs say - it can auto discharge up to +/- 50v and for a cap that is less than 10uF the absolute maximum it can withstand is +/- 275v, over 10uF that is +/- 50v **Q: Can this unit be used to test capacitors in circuit (without unsoldering)?** A: Atlas ESR can be used in the circuit. For this reason, also be measured without removing the capacitor from the substrate. Of course, even if you test a capacitor is removed from the circuit, can be measured. **Q: so it only checks capacitance of .1uf or higher?** A: Its capacitance measurement range is 1uF to 22,000uF with 0.2uF accuracy. ## Frequently Bought Together - Velleman Atlas ESR70 Capacitance and ESR Meter - Velleman DCA55 Semiconductor Analyzer - Peak Atlas LCR45 LCR and Impedance Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/575508483-atlas-esr70](https://www.desertcart.co.uk/products/575508483-atlas-esr70) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-05-02*
