The Ashcroft C-600B Duratemp is a direct-mount gas-actuated thermometer designed for extreme temperatures and high-vibration environments. Its movementless mechanism eliminates wear, ensuring long-term reliability where bimetal thermometers would quickly fail. Temperature ranges extend from cryogenic -320°F up to 1200°F, exceeding the limits of most bimetal instruments.

The 4.5-inch stainless steel case houses a 360° rotatable display, allowing the dial to be positioned for optimal viewing regardless of installation orientation. The Maxivision dial eliminates parallax error, providing accurate readings from any angle. Overrange protection to 125% of span safeguards the instrument during process upsets. Gas-actuated molecular sieve technology ensures stable performance.

Typically installed with a thermowell, the C-600B is suitable for refineries, chemical plants, power generation, and general industry. Custom dials and ranges are available to match specific application requirements.
