Capacitor ESR Meters

Aluminium electrolytic capacitors have a relatively high ESR that increases with age, heat, and ripple current; this can cause the equipment using them to malfunction. In older equipment, this tended to cause hum and degraded operation; modern equipment, in particular switch-mode power supplies, is very sensitive to ESR, and a capacitor with high ESR can cause equipment to malfunction or cause permanent damage requiring repair.An ESR meter is a two-terminal electronic measuring instrument designed and used primarily to measure the equivalent series resistance (ESR) of real capacitors—the ESR of an ideal capacitor is zero.We Have Done Extensive Research In This subject And Have Used And Experimented With Most Of the Open Source and Commercial Solutions Out There .The Products We Sell Are Used And Have A Good History .
