The Ashcroft C-600A-03 Duratemp is a remote-mounted gas-actuated thermometer engineered for applications requiring maximum durability and resistance to shock and vibration. Its movementless design contains no gears to wear or misalign, eliminating mechanical failure points and significantly increasing instrument life.

The thermometer provides ±1% full-span accuracy in compliance with ASME B40.3 standards. Unlike conventional systems, the gas-actuated mechanism introduces no head or elevation error due to bulb position, ensuring accurate temperature transmission regardless of mounting orientation. The large Maxivision® dial places the pointer on the same plane as the graduations, completely eliminating parallax for reliable reading from any angle.

Available in 4.5-inch and 6-inch black coated aluminum cases with aluminum threaded rings, the C-600A-03 accommodates a wide selection of temperature ranges from -320°F to 1200°F with 125% overrange protection. The 316 stainless steel bulb measures 3 inches long by 3/8 inch O.D., connected via 5 to 80 feet of capillary tubing with optional armor choices including AISI 302 stainless steel spring armor or PVC-coated protection.

Typically installed with a thermowell, the Duratemp is ideal for high-vibration environments such as compressors, pumps, and engine skids, as well as extreme temperature applications in refineries, chemical plants, and power generation facilities. The remote mount capability allows operators to monitor process temperatures while maintaining safe distance from hazardous areas.
