This temperature gauge is the highest quality available on the market today, bar none! It is the only substantiated laboratory tested gauge that has no equal. Not that you'll need it, the thermometer is waterproof to 165 feet. It features a stainless steel chrome case with a black face, white hands and numbers. The thermometer mounts on any 1/4, screw or bolt, works great on switch housing screws or windshield acorn nuts.
