100kHz ESR Meter for Vintage Audio Repair UK
Answer first: A 100kHz ESR meter for vintage audio repair uk work should show capacitance with ESR/D together so tired electrolytics are not judged by capacitance alone.
Vintage audio repair fails quietly when ESR rises. A portable LCR meter with sorting and calibration routines keeps that check repeatable.
The LCR Meter UK portable digital LCR meter offers up to 100kHz test frequency, dual-parameter colour TFT readout, auto L/C/R identification, ESR and D measurements, sorting, Kelvin clips, open/short calibration and USB-C rechargeable operation, listed at £88.01.
Frequently asked questions
Why 100kHz for electrolytics?
Higher test frequency reveals ESR behaviour that a DC resistance check will miss.
Should I test capacitors in-circuit?
Often no—parallel paths confuse readings. Lift one leg when practical.
What is dissipation factor D?
A loss indicator that complements capacitance when ageing capacitors look “still in range”.
Do Kelvin clips matter on the bench?
They reduce lead resistance errors on low ESR and low impedance parts.
