Description
Real-time water pressure monitoring is critical for engine reliability, especially under racing conditions where coolant system failures can end your day—or worse. The Longacre Waterproof SMI Water Pressure Gauge delivers dependable analog readout with sealed electrical construction, so you get accurate pressure data whether you’re on the track or in the shop. Its stepper motor mechanism ensures smooth, repeatable needle movement without the lag or drift common to mechanical gauges.
This gauge integrates seamlessly into custom dash setups and works with most data acquisition systems. The waterproof SMI design handles harsh environments, vibration, and thermal cycling that would compromise standard instruments.
