A water-tight thermometer is constituted by a body member and a tip member secured thereto. The body member includes a display portion with a display aperture and a probe portion secured thereto. A thermal sensor mounted on the inside of the tip member is adapted for sensing a thermal contact surface and producing a temperature signal. A display unit disposed in the display portion receives the temperature signal for display of a corresponding temperature reading. And a transparent layer with a protrusion extending from an upper surface thereof at least covers the display unit under the display aperture. In particular, an outer wall of the protrusion is closely engaged with an inner wall of the display aperture.
