ESUPPORT 2" (52mm) Digital Water Temperature Gauge — Fahrenheit Display, Warning Light

ESUPPORT 2" (52mm) digital water temperature gauge quickly reads engine coolant temperature in Fahrenheit and triggers a warning light above 212 °F.

This compact 52mm instrument delivers continuous, easy-to-read coolant readings for cars, trucks, and custom projects. Engineered for DC 10–15V systems (nominal 12V), it pairs a clear digital display with a dedicated NPT 1/8" sensor connection so you can monitor temperatures between 104 and 300 °F and get an audible/visual prompt when temps climb above the preset 212 °F threshold. The slim 2" size fits standard dash pods and aftermarket gauge clusters while offering reliable operation for daily driving, towing, or track use.

How accurate and wide is the temperature range?

The ESUPPORT gauge covers a broad operating window from 104 to 300 °F, suitable for most automotive cooling systems and performance setups. Readings are displayed digitally for quick interpretation at a glance.

• Operating range: 104–300 °F
• Warning light activates when temperature exceeds 212 °F
• Digital display for precise numerical readout

What electrical and mechanical connections are required?

Designed for standard 12V vehicle electrical systems, the gauge installs using a DC 10–15V power source and connects to the included NPT 1/8" sensor. Wiring is straightforward for experienced DIYers or professional installers and integrates cleanly with dash harnesses.

• Operating voltage: DC 10–15V (nominal 12V)
• Sensor mounting: NPT 1/8" thread for coolant ports
• Compact 2" (52mm) housing fits common pods and panels

How does the warning light function during high temps?

The gauge features a built-in warning indicator that illuminates when coolant temperature surpasses 212 °F, giving you a fast visual cue to check engine conditions. This helps you react sooner to overheating risks without relying solely on driver intuition.

• Warning threshold preset at >212 °F
• Immediate visual alert on the gauge face
• Useful for towing, spirited driving, and early detection

What dimensions and fit should I expect for installation?

The gauge measures 2 inches (52mm) in diameter, making it compatible with most aftermarket dash pods and mounting brackets. Its compact form factor leaves room for additional instruments and simplifies placement in tight instrument clusters.

• Face diameter: 2" / 52mm
• Panel cutout accommodates standard 52mm mounts
• Low-profile housing ideal for dashboards and consoles

Who is this for: The ESUPPORT 2" digital water temperature gauge is aimed at drivers who want a clear, dependable coolant temperature readout—enthusiasts, daily drivers, and light-duty commercial users who need quick warnings of overheating during towing, track days, or stop-and-go traffic. It suits anyone fitting aftermarket gauges into a 52mm pod, installers who prefer a digital numeric readout with a dedicated warning light, and DIYers adding a reliable temperature sensor to older vehicles or custom builds.
