Hoyt HST-75 2.5-inch Analog DC Ammeter, 100 A

Hoyt Meter’s HST-75 series uses a compact 2.5-inch rectangular analog format with a clear black knife-edge pointer for at-a-glance monitoring at the electrical panel. This DC ammeter displays a 0–100 amp scale from a 0–50 mVDC input. It must be paired with a 100 A/50 mV external shunt, such as Common Ground Marine SKU CSH-LA-100-50; it does not carry or measure the full circuit current directly. The combination is intended for marine DC electrical panels where operators need a straightforward view of charging or load current. Install the shunt in the measured circuit and run the low-level sense leads to the meter according to the supplied documentation. Common Ground Marine also supplies select HST configurations with custom ranges and scales for specialized marine panel applications.
