High-temperature bimetal thermometer

The Dwyer Instruments BTM3608D is a dial thermometer designed for measuring temperatures from 150 to 750 degrees Fahrenheit, with a Celsius equivalent of 65.5 to 398.9 degrees. It serves technicians and operators who need direct, local indication in high-heat industrial processes.

Stainless steel housing

The instrument features a stainless steel housing and a glass lens protecting the 3 inch dial. A 6 inch stem extends from a 1/2 inch NPT back mount, allowing permanent installation into threaded process fittings or thermowells for continuous monitoring.

Mechanical operation without external power

As a bimetal device, it operates purely through thermal expansion of bonded metals, requiring no electricity, batteries or signal wiring. The dial provides immediate reading but cannot transmit data remotely, and the fixed range limits use to processes staying within the 150 to 750 degree Fahrenheit window.
