Dyno Racing 2" 52mm Water Temp Gauge 40-120°C 30mm Adapter

Gauge and adapter for 12 V cooling systems

The Dyno Racing 2" 52 mm water-temperature gauge measures coolant from 40 to 120 °C and is designed for 12 V DC electrical systems drawing up to 0.3 A. A white LED backlight illuminates the black face so the pointer and numbers remain readable in darkness. The package includes a 1/8 NPT sensor, a 30 mm joint pipe, two stainless-steel clamps and English instructions.

Passive analog operation with LED backlight

The gauge uses a mechanical pointer driven by the supplied sensor, so it adds no active cooling load and generates no fan noise. Power consumption is limited to 0.3 A at 12 V, placing minimal demand on the vehicle charging system. The white LED dial light operates only when the ignition is on, providing visibility without contributing to parasitic draw.

Direct-fit sensor and hose adapter for simple

A 1/8 NPT threaded sensor screws into an available port on the engine or radiator, while the 30 mm joint pipe clamps onto the existing coolant hose using the two supplied stainless-steel clamps. The adapter’s internal diameter suits hoses near 27 mm, and the supplier notes that 28, 32, 34, 36, 38, 40 and 42 mm sizes are also available if a different fit is required.
