Battery capacity tester from Meco

6390

MECO Meters Pvt. Ltd., has launched a battery capacity tester 6390, designed for measuring the internal resistance, open circuit voltage and terminal temperature of secondary battery including Nickel-metal hydride battery (NiMH), Nickel cadmium battery (NiCd), Lithium-ion battery (Li-ion), alkaline battery and lead-acid battery. The new battery capacity tester uses AC four terminal -method to measure internal impedance which it does by eliminating lead impedance and contact impedance in a bid to get the accurate results. The meter is claimed to measure resistance from 4mΩ to 400Ω with minimum resolution of 1μΩ. Voltage measured by 6390 is up to 60V with resolution up to 1mV. The meter has been tested to operate in temperatures from (-) 20 degree Celsius to 60 degree Celsius. The key highlight of the compact and light weight meter, is a dual display that displays both the internal impedance and voltage of the battery simultaneously. Boasting of 99 sets of composite comparator function, it (meter) can be set at impedance and voltage values, and can accurately detect battery deterioration. Pin type leads, which can easily contact the battery electrodes, are supplied as standard to offer accurate four-terminal measurement. Other features include a memory and read function, manual data logging (999 Data sets), and online testing without the need to shut down the battery. A user interface software additionally connects the meter to a PC using the RS232C Cable.
