The Autometer ES 52mm mechanical water temperature gauge uses a Bourdon tube movement to provide rapid, accurate temperature readings and includes a 6‑inch capillary tube, 1/2″ NPT adapter and mounting hardware. Modern red LED through‑the‑dial lighting improves nighttime visibility, and the mechanical design operates without vehicle electrical power, making it suitable for street and race applications where reliable, direct temperature feedback is needed.
