These thermometers, fabricated of quality materials, work on a conduction-radiation principle. The base of the unit is placed on the surface to be measured. Heat is transferred to the inner chamber of the unit, which contains a bimetallic sensing element. Radiation from the base inward causes the sensing element to react, with resulting dial readout.
Easily and quickly installed. For nonhorizontal areas,the bottom of the unit is coated with a thin layer of silicone grease and the unit is pressed into position. The grease will hold the thermometer in place on ferrous surfaces and a magnet and leaf spring holds the instrument firmly against the surface. These instruments are fully enclosed to protect the bimetal from dirt and dust. |
