U.S. Gauge offers 3” and 5” heavy duty, industrial bimetallic thermometers with a versatile case and stem that can be adjusted to almost any angle for easy viewing.

The head can be rotated 360º and the stem positioning moves over 180º. These thermometers are rugged and preferred by the process, offshore, power, pharmaceutical, and chemical industries. The union connection is 1/2-14 NPT, but others are available.

The thermometers may be silicone filled for additional vibration dampening. A variety of lens materials are available including acrylic, polycarbonate, shatterproof and tempered glass. Standard stem diameter, up to 42” long, is .25”. Other available stem sizes are .24” (6 mm), .32” (8 mm), and .375” (9.52 mm).
