Cole-Parmer Industrial Silicone Filled Bimetal Thermometer, 3” Dial, Adjustable Angle, 4” Stem, 0-250°F (-20-120°C)

Description

This Cole-Parmer industrial thermometer is a mechanical instrument for monitoring temperature in process and laboratory settings. It operates on a bimetal sensing principle, where a coiled strip of two bonded metals expands at different rates with heat, causing the coil to wind or unwind and move a pointer on the dial. The device features a 3-inch dial for clear visibility and is calibrated for a dual-scale range of 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius. Its stem measures 4 inches in length, suitable for immersion into tanks, pipes, or other vessels. A functional design element is the adjustable-angle connection between the stem and dial housing, which can be rotated after installation to provide the most convenient viewing angle. The internal mechanism is filled with a silicone fluid that dampens vibration and reduces pointer oscillation, contributing to stable readings and increased durability in industrial environments.
