Swagelok® Thermometers
Obtain reliable temperature readings and with easy-to-use Swagelok dampened-movement bimetal thermometers.
Request More InformationSwagelok® thermometers are built with hermetically sealed cases that comply with ASME B40.200 standards, preventing fogging and moisture damage to internal components. They are factory-calibrated to meet ASME B40.200 specifications and offer 50% over- and under-range protection for internal components up to 500°F (260°C). Silicone-free gel inserts reduce vibration effects.
These thermometers come with a variety of lenses including acrylic, glass, polycarbonate, and safety-glass, catering to different application needs. They feature a standard all-welded 304 stainless steel construction with an option for 316 stainless steel process connection and stem. Anti-parallax dials ensure easy reading, and external adjustment allows for straightforward field calibration.
Optional features include no dampening, NIST-traceable calibration certificate, silicone liquid fill (not available with standard dampening, glass lens options, or for dial ranges over 500°F [260°C]), 316 stainless steel process connection and stem, and an NPT union lock nut.
