Usage Scenario

Tom noticed his old car was running hotter than usual but the factory dashboard did not show exact coolant temperature. He installed this 52mm water temperature gauge in the dash panel, connected the included sensor to the engine block, and set the alarm to alert him if the temperature climbed above 100 degrees Celsius. Now he can see the exact reading in bright green backlight at night and drive with confidence knowing he will get a warning before any overheating issue gets serious.
