Programmable Ampere-Hour Meter

Amp-hour meter, Model 800AH from Countronics, an ISO 9001:2000 certified company, is a micro-controller based precision product designed to integrate and display DC current flowing with respect to time. It becomes a measure of the total current energy. A preset limit of this integrated current can be pre-programmed and when the limit is reached, a relay is switched On to trigger an alarm. For different ranges, the shunt resistance is user programmable up to 9999 A at 75 mV. In addition, an internal limit of 10.5 V is preset so that a 12 V battery can be tested for its A-H. As soon as the 12 V battery discharges to a voltage below 10.5 V the Amp-Hour meter stops automatically. The equipment can be used for Amp-Min also. The instrument reads current and integrated current up to 999999 A. Resolution of 0.1 A-H and 0.1 A-Min is also available. The 96 x 96 mm light weight ABS cabinet with front panel membrane switches and bright 7-segment LED displays makes it attractive and rugged. It is essential for maintaining a constant thickness in electroplating irrespective of fluctuations in voltage and current, displaying the direct current using a shunt calibrated for 75 mV and for checking the Amp-Hr rating of a battery.
