High precision battery internal resistance and test meter

Product description

The device is used to measure the internal resistance of cells, batteries, resistors and other components. Four-wire and four-point 1 kHz AC-sinusoidal digital meter of internal resistance and battery voltage in the range of 0.00001 ohm to 200 ohm and 0 V to 100 V, designed for measuring batteries of type Pb, Li-Ion, Ni-MH, Li-Pol, LiFePO4, Ni-H2, Ni-Cd, as well as alkaline and dry cells, button cells, resistors, etc.

About this product

  • Digital LCD display, easy to read the measurement result. With backlight, it makes it easy to read in low light areas
  • Adopt 4-wire method which helps to ensure the accuracy of the measured value
  • True four line 1Khz AC sinusoidal battery internal resistance instrument 0.00001 ohm - 200 ohm range
  • Test range up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.
    Press HOLD to enable the ZR function to measure internal resistance as low as 0.30--0.50 milliohms.
  • It is applicable for measurement of internal resistances of Lithium-ion, Pb, Li-Ion, Ni-MH, Li-Pol, LiFePO4, Ni-H2, Ni-Cd cells or assembled battery

    Using battery internal resistance meter

    The device is used to measure the internal resistance of batteries and voltages of a maximum of 100 V and only direct current. The device can also measure the resistance of resistors in the circuit and other components. In this case, make sure that such a circuit is not under load. Failure to follow these instructions may result in irreversible damage to the device.
