Analogue gauge measures coolant temperature across a 100 to 250 degrees Fahrenheit range. DC 12V operation and an included temperature sensor support quick electronic readings.


Clear night-time readings - with LED backlight

Backlit dial illumination raises contrast between the numbers and pointer, making the gauge visible from different viewing angles. The LED lighting remains highly visible under white light for safe monitoring after dark.

Safer night driving thanks to easy-to-read temperature indications. Glanceable display reduces distraction when checking engine temperature on the move.

Accurate coolant monitoring - with an electronic temperature sensor

An electronic temperature sensor connects to the gauge to convert coolant temperature into an analogue readout across 100-250°F. Electronic circuitry delivers fast, stable readings suitable for real-time monitoring.

Early detection of rising coolant temperature helps prevent overheating. Reliable readings give confidence during long runs, towing, or heavy traffic.

Robust fit and finish - thanks to ABS construction and solid cover

Housing made from ABS material resists high temperatures and fading, while user feedback highlights a durable glass cover and sturdy build. The gauge's construction supports long-term use in automotive environments.

Durability reduces the need for replacement, even under regular use. A solid build gives peace of mind for drivers who expect a long-lasting accessory.
