Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. The Atlas ESR offers instant results. Just connect the probes and press test - no need to worry about polarity! You can even use the Atlas ESR in circuit, saving you the trouble of removing capacitors. When testing capacitors out of circuit, the unit will also display the capacitance. If a capacitor is charged, the unit will automatically carry out a controlled discharge procedure before measuring the capacitance and ESR. Audible feedback during testing provides indication of high or low readings. Includes GP23A 12V battery. Dimensions: 100 x 70 x 20mm.


  • Dynamic range of 0.00 to 40.0Ω

  • Supports 1µF to 22,000µF
  • Ideal for low DC resistance checking (such as PCB shorts)
  • Industry standard 100kHz test frequency
  • Long life battery included
  • Polarity free connection
  • In-circuit measurement
  • Capacitor discharge function
