Sierra 68389P Eclipse Ammeter Gauge, 2 Inch, 60-0-60 Dial Range, Scratch Resistant Glass Lens

The Sierra 68389P is a 2 inch ammeter gauge from the Sierra Eclipse series, built to monitor charge and discharge current on a boat's electrical system. Its 60-0-60 dial range shows amperage in both the charging (positive) and discharging (negative) directions, with zero centered for an at-a-glance read of battery condition. The gauge face is protected by a domed glass lens that is scratch resistant, helping keep the dial legible and clear against sun, spray, and everyday wear at the helm. Sierra is a Teleflex marine brand that has supplied engine, drive, and instrumentation parts to the marine industry for decades, and the 68389P carries Sierra's standard build quality for dash-mounted gauges. The compact 2 inch dial size makes it suited to helm panels and dash layouts where space is limited, and it pairs with other Sierra Eclipse series gauges (voltmeters, tachometers, water temperature and oil pressure gauges) for a matched instrument panel look. The unit uses NPT thread fittings and is identified by UPC 808282266738 for easy reordering.
