Velleman Atlas ESR70 Capacitance and ESR Meter

This is a high quality product that is accurate and easy to use. The fact that the meter is made in England resulted in a well written instruction booklet and not a fractured English translation. It only takes seconds to test a capacitor. The ESR feature is the soul of the product. The cap may still test good, but the ESR will warn you if its future is limited. That will save you a lot of time and work.

I was unsure about purchasing this ESR meter. Its price was a little high and with a few pieces of test equipment you can basically do the same type of check on a capacitor. I did however purchase this item and I was glad that I did. All the necessary setup work and math are all encapsulated in one package. Simple turn the unit on and you are ready to go. I have used this in troubleshooting capacitors in a cement mixer as well as all of the capacitors in my Commodore 64 and Atari 2600. It really is a nice to have tool in your arsenal. The build quality is good, as well as the battery life, speed and functionality.There is somewhere buried in another amazon review a 3D print file for a stand that I found to be very useful.

I rarely write reviews unless a product totally needs recognition. This is the best Capacitor ESR meter that I have used. Truly saves you time by implementing in circuit testing. I have tried many Chinese capacitance testers and got fed up with the false data they presented so I broke the bank and bought this. Can’t say it was a bad purchase because it totally changed my life. I have cut my trouble shooting to 1/4 the time by having a unit that accurately tests in circuit. No more desoldering capacitors to test them. On rare occasions only you might have to lift a led to test. Simply accurate in every way. The best part is it discharges a capacitor before testing. This unit is a must for bench techs everywhere. Yea I know it is not cheap but I would not waste time with a review if it was useless like the TC1.

The function is very good. The clips could be better. They are not heavy duty, the tension is average and the nose and teeth are too large for many areas. You can "bite" a pin out of a DMM for tighter clearances, but for the money the quality should be better and a pin an included option. The readout is accurate and quick, no complaints with that aspect.

Works perfectly with in place capacitors. Best refurbishing tool for my tool box.

I am so tired of cheap Chinese garbage everywhere. Nothing works. Bought some ESR, paid 60$, measure same capacitor 3 times - each time different reading. Returned - this thing is awesome. It not only made in England, it actually works. Same capacitor shows the same uF and ESR even if you measure it 20 times. It discharges capacitors automatically, it shows you capacitance and ESR, it shows when capacitor is shorted, it has long nice alligator probes and they can be removed and used with something else. Well worth the money.

Muy bueno y util para saber el estado de los electroliticos.

I was initially skeptical about the accuracy of the capacitance reading after measuring a few capacitors I have laying around. There is a youtube video out there though where someone compares this against a couple of other reputable measurement devices with favorable results. I did realize there is a calibration procedure as well so I'm more of a believer now. The leads are smaller than I thought but that's ok because I have very small components to measure on some circuit boards. I should be able to take the clips off and poke with the ends of the leads well enough. I always start my meter and tool searches for used, not "made in China" stuff so I was happy to see this was new and made in the UK.
