Need to keep an eye on temperatures in a tough environment?

This Industrial Stack Thermometer is built for the job.
It's a no-frills, rugged gauge designed for things like furnaces, ovens, boilers, smokestacks, or any industrial process where you need to monitor heat.

The large 3-inch dial is easy to read from a distance, with a clear scale ranging from 200 to 1000 degrees Fahrenheit.
It comes with a 6-inch stainless steel stem (that's from the top of the threads to the very tip) that you insert into whatever you're measuring.
The connection is a standard 1/2-inch NPT (National Pipe Thread), which makes installation straightforward—just screw it into a compatible fitting or port.

The whole thing is constructed from stainless steel, so it can handle high temperatures, corrosion, and general shop or factory wear and tear.

It also has an external reset feature, which is handy.
