Temperature Thermometers

Explore Ashcroft® temperature thermometers for your specific application.

Ashcroft® bimetal thermometers and gas actuated thermometers provide easy-to-read temperature measurement on a dial indicator. Both operate without the use of mercury. Bimetal thermometers are actuated by a helical bimetal while gas-actuated thermometers use expanding or contracting gas in a closed bulb and capillary system. Bimetal stems and capillaries along with associated thermowells are available in a wide selection of lengths to fit nearly any application

Types of Thermometers

Ashcroft offers a broad range of industrial thermometers engineered to provide accurate, reliable temperature indication across process, industrial, OEM, and hazardous applications. Available in bimetal and gas actuated designs with direct and remote mount configurations, Ashcroft thermometers are built to withstand demanding operating environments.

Bimetal Thermometers – Provides accurate, maintenance-free temperature indication using a rugged helical bimetal sensing element for industrial and process applications.

Gas Actuated Thermometers – Delivers reliable temperature indication across long distances using a gas-filled bulb and capillary system, making them ideal for remote mounting and difficult-to-access installations.

Direct Mount Thermometers – Intended for applications where the thermometer is installed directly at the process connection for convenient local temperature indication.

Remote Mount Thermometers – Provides temperature indication away from the process using a capillary system, helping reduce the effects of vibration, heat, and limited accessibility.

Liquid-Filled Thermometers – Minimizes pointer flutter and improves readability in applications with vibration and pulsation.
