Ashcroft 600A-01-C11-B01-A1-L03-AL Dial Thermometer

Ashcroft 600A-01-C11-B01-A1-L03-AL Duratemp Dial Thermometer is a 4.5-inch gas-actuated dial instrument designed for direct-panel mounting with a flush-mount rear connection and a stainless-steel bayonet ring. The bulb assembly uses a 12-inch bendable extension with a 1/2 NPT union (B01), paired with an A1 stainless-steel spring for durability, and a 10-foot capillary line (L03) to position the sensing bulb where needed. It taps into a temperature range designated by AB as -320 °F to 200 °F, making it suitable for demanding industrial processes. The AL suffix is part of the model configuration for this Duratemp series unit. Duratemp instruments use a movementless gas-actuated mechanism to resist shock and vibration and to extend service life in harsh environments. This combination of a 4.5-inch dial, rear-connection flush mount, and extended sensing options makes it well-suited for process temperature monitoring where a robust, readable indicator is required in panel installations.
