Thermowells

Thermowells for sanitary applications as well as thermowells that can be treated and documented to NACE standards. Thermowells are recommended for pressure, corrosive fluid, or high velocity applications. Produced using highest quality material and machined from solid bar stock for standard or high velocity requirements in a large selection of materials and coatings. Designed and manufactured to assure perfect alignment with the thermometer stem.

Glass Industrial

Our glass industrial thermometers are versatile and adjust-angle, with a lens front and red liquid fill. They are NIST calibrated and guaranteed accurate to ± one scale division.

Tariff Policy

We understand the concern regarding tariff-related costs and we share the same frustration—no one benefits from rising input costs. While certain tariffs have been challenged or removed, the tariffs on steel and aluminum remain in place and continue to impact the materials used in many of our products.

Over time, these tariffs have been incorporated into the pricing from our raw material suppliers, meaning they are now embedded in our overall cost of goods rather than listed as a separate surcharge. Because of this, we are no longer able to isolate or reverse specific tariff charges on individual orders.

We have actively explored domestic and alternative sourcing options in an effort to mitigate these increases; however, we have not yet found materials that match the performance, quality, and reliability required for our products.

Please know that we remain committed to managing costs responsibly while continuing to deliver the quality and precision our customers rely on. We truly appreciate your understanding and your continued partnership.

If you have any questions or would like to discuss how we can help you, please don’t hesitate to reach out.

Thank you for choosing Tel-Tru.
