10 Best Esr Meter of December 2025

• Using true 100 KHz sine wave to measure the ESR value, which is equal to the testing method of capacitor manufacturer.
• Dual terminal, for fast and easy inspect general capacitor or resistor, a printed ESR table for fast check.
• Measuring range from 0.001 to 100.0R, support IN CIRCUIT Testing.
• Auto-ranging capacitor ESR and Low Ohm Meter.
• Wide Measurement Range

Signstek

• It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).
• The impedance become small, and we can then measure the true series resistor value.
• Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
• Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test.
• During repairing TV, LCD, Audio board, etc. we can in circuit testing the capacitor is good or not.

Roeam

• Tests ESR of >1uF electrolytics in circuit
• Non polarized test leads with resistance compensation
• Automatic power off when reading is unchanged for 3 minutes
• Easy-to-read high brightness 0.5 inch (13mm) piercing blue LED display
• Full 1yr warranty for manuacturing defects

WERF

• Test ranges:Inductors, capacitors , diodes, dual diode , mos, transistor, SCR , the regulator, LED tube, ESR, Resistance, Adjustable potentiometer
• Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage.
• High test speed, valid component test: 2 seconds (except in the larger capacitor of large capacitance measurement also takes a long time, the measured time of one minute is normal)
• 128*64 big Backlight LCD display,only 2mA when stand by.
• Auto power off function to avoid unnecessary waste, saving battery power, improved battery life

AITRIP

• For detecting NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery, etc.
• Can also be used to detect infrared wave forms.
• After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.
• One button operation, automatically detect and shutdown, and you can also press the multi-functional button to close the detector.
• Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.

ICQUANZX

• LCD DISPLAY ENSURES CLEAR READING--3000 count LCD display
• HANDHELD RESISTANCE TESTER OFFERS CONVENIENT OPERATION--The tester is a handheld and battery operated very convenient small Tool that is specially used to measuring SMD
• AUTOMATICALLY IDENTIFIED CAPACITANCE TESTER--The tester is automatically identified the passive component
• AUTO POWER OFF PROVIDES ECONOMIC USING--Auto Power OFF. If the tester is idle for more than 10 minutes, the tester will automatically turn off the power
• PREMIUM QUALITY MATERIAL ENSURES GOOD DURABILITY AND NICE APPEARANCE--The entire outer surface of the tester case has been with thermo plastic elastomer, and the two testing pins has been gold-plated, so that it is reduce pin contact resistance and prevent to get rusty

Wal front

• This LCR Meter is a 19999/ 9999 counts dual display, high accuracy LCR meter, which could measure Inductance/ Capacitance/ Resistance with secondary parameters including dissipation factor (D), quality factor (Q), phase angle , equivalent series/ parallel resistance (ESR or Rp).
• This LCR Meter is fully auto ranging operation for AC impedance & DC resistance measurement. The user could measure the L/C/R components directly in “AUTO-LCR “ smart mode without selecting the function key.
• Components could be measured in serial or parallel mode according to the DUT (device under test) impedance automatically.User could select the desired test frequencies of 100Hz/120Hz/1kHz/10kHz /100kHz.
• The "Sorting"mode could help the user to make a quick sort for a bunch of components.
• Standard Accessories: English PDF manual, DC9V Battery, Alligator test lead case(TL-21), SMD Tweezers case(TL-22), Guard Line(TL-23),,,,, Option: IR to USB cace *It isn't included.
