Echo Therm manufactures mercury-free glass and industrial thermometers in Springfield, Ohio. Built to last, backed by nearly 80 years on the same manufacturing floor, and shipped in weeks, not months.
Most domestic glass thermometer manufacturers are gone — offshored or closed. Echo Therm has been on the same manufacturing floor in Springfield, Ohio since 1947. That means domestic production, domestic lead times, and no container ships in your supply chain.
Importing usually means paying in full up front and waiting on overseas shipping you can not control. Producing domestically keeps that timeline in your hands. Echo Therm turns orders around quickly and keeps you in the loop, so your shelves and your customers never wait.
From plant floors to processing lines to healthcare facilities, distributors and buyers count on Echo Therm for thermometers that perform.

Quality materials, selected to standard.
Crafted in Springfield, Ohio.
Accuracy verified, unit by unit.
Inspected against our standard.
Packed and out on a domestic timeline.
Every tube is aligned and inspected by hand in our Springfield, Ohio facility before it ships.
The freeze indicator trusted across the cold chain is now manufactured by Echo Therm. A single-use ampule that fractures and permanently stains its backing when a shipment hits freezing, so you know at a glance if temperature-sensitive product was exposed in transit or storage.
Straight answers about our products, specs, and how we work.
Echo Therm uses a non-toxic, mercury-free liquid fill across all product lines. It will not fade, separate, or break down under normal use — unlike kerosene-based fills common in imported alternatives.
We manufacture tubes from 1.5" to 24" in overall length, with a range of diameters and scale options. Custom dimensions are available — tell us the application and we will spec the right tube.
Both. We offer finished ready-to-sell thermometers with custom scales, bare tubes for customers who mount them in their own housing, and custom-assembled units with your printed scale.
Standard accuracy across our product lines is ±2°F. For applications requiring tighter tolerances, let us know in your quote request and we will discuss what is achievable for your spec.
We ship to the United States, Canada, Mexico, Australia, and Europe. Domestic orders ship on a much faster timeline than overseas alternatives — typically weeks, not months.
