Electronics International Hour Meter
Records Time; Activated by Oil Pressure Switch
Hour meter (similar to Hobbs) activated by oil pressure switch, records engine time. System requires ordering both components (Meter and switch) separately. Optional oil pressure switch can be wired to run Hour Meter and illuminate a panel light if the oil pressure drops below 15 psi. Besides being a monitor should you loose oil pressure, this effectively works as a warning to turn the Master Switch off when the engine shuts down provided a large enough red light is mounted on the panel.
