BVIR battery internal resistance tester
NEWARE BVIR battery internal resistance tester is the high precision internal resistance tester designed for rechargeable batteries (including lead-acid, nickel cadmium, nickel metal hydride, lithium ion,lithium polymer batteries). It can also test the battery voltage.It’s operate simple, reliable,and the rate of performance/ cost is high. It’s been widely used in scientific research institutions, producter, distributor of rechargeable batteries.

BVIR system features:
Adopt measure methods according to GB / T 11013-1996 and IEC 61436:1998 standard, the result of measurement is more accurate and reliable;
Measure the battery’s Alternate Current internal resistance directly and quickly;
Characteristic by simple circuit, high integration, powerful anti-interference ability, measured with a constant AC less than 20mA, stable and reliable performance;
High-end digital display tube, the data show stable, easy to read;
Customized test cable, reduce errors;
Voltage, resistance show with 3 .5-digit table display, automaticly switching resistance, voltage range, no need to change range,easy to operate;
The internal resistance and voltage of cell or battery can be tested at the same time ,measurements also show a wide range , can be used for various types of batteries and battery packs that the voltage is less than 20V;
Beautiful appearance, solid structure, small size, easy to carry
