Portable Battery Tester for Storage Batteries

Mobile battery tester for voltage measurement; measurement for the electrical internal resistance and the electrochemical impedance of a battery block; capacity test via logging of current values and voltage curves; integrated Bluetooth interface, integrated IrDA interface for connecting a DMA35 density sensor, RFID transponder function (125 kHz).


The METRACELL is a mobile and multifunctional test device for the evaluation and maintenance of battery systems and uninterruptible power supplies (UPS), for example in computer centres, hospitals or power stations. Due to its small size, the measuring device can be easily attached to the technician's belt or worn around the neck on the enclosed belt. The METRACELL can be used to measure the voltage as well as the electrical resistance and electrochemical impedance of a battery block. Capacity tests can be conducted through logging of current values and voltage curves. The device stores up to 30,000 data records, which can be managed with the supplied battery management software and output as CSV in the form of informative reports.
