This compact 1732200 mini DC ammeter from Blue Sea Systems utilises a high quality, crystal clear blue OLED display that is readable even in bright daylight conditions. Its compact form means that it can be mounted in any convenient location and its waterproof design allows it to be used on deck for easy battery monitoring.  It has reverse polarity protection to prevent damage due to incorrect wiring and can be used in either 12V or 24V systems.

The ammeter display comes with a 100A/50mV shunt (Blue Sea Systems part no. 9230) that can measure current on either the positive or negative side of the circuit(s). The shunt is rated at 100A but it is recommended that the current should be limited to 66% of this (66A) if it is to be run continuously.

This ammeter can be used to measure the current output of, for example, an alternator or battery charger, or it can be used to measure the current consumption of specific loads or of the entire system (within the current limits of the shunt). Download the instructions from the 'Manuals & Guides' tab for installation examples.

IMPORTANT: Blue Sea Systems recommends the use of a 2A fuse in the positive power supply cable to the meter and 1A fuses in both wires between the shunt and the meter if the shunt is being used on the positive side of a circuit.
