The Sentry Temperature Sensor is an optional sensor with a 12 inch extension, detecting temperatures above 120 degrees Fahrenheit.
A 120 degree threshold is set well above normal ambient but below the point where damage is done, which is what makes it useful as an early warning rather than a fire alarm. In a battery compartment, an engine space or an equipment locker, heat rising past that point usually means something is failing before it fails completely.
The 12 inch extension lets the sensing element be placed at the actual hot spot while the body stays where it can be wired conveniently. Sentry notes this cannot be returned to the point of purchase, so any issue goes direct to the manufacturer rather than the retailer. Explore more marine gauges.
