The TriMetric Battery Monitor The TriMetric battery monitor is designed to assist in battery care, conservation and system maintenance of battery powered systems that use storage batteries with system voltage from 12-48 volts. It provides the user with information on battery "volts", "amps" and "amp-hours" and "battery percent full" information, based on measuring the amp-hours removed from the battery system. Reliability, accuracy and simplicity are key product objectives. The TriMetric requires an external shunt located near the batteries to measure "amps" and "amp-hours". The meter readout may be located hundreds of feet away from batteries and is usually connected to the shunt with a 4 wire cable. “Suggested retail” price is $169, not including the “double gang” electrical box shown above, or necessary shunt. Cost with these will be less than $200. Click Here For More About The TriMetric...

Optional computer interface with (Windows) software to control and read out all data. Extensive system logged data Relay output to control generator or external alarm Audible and visual alarms for high and low battery conditions System cost: from about $320 (with computer interface only) to $519 (with everything except shunts, temperature sensor and interconnection wiring).
