Cole-Parmer Industrial Bimetal Thermometer, 3” Dial, Back Connect, 4” Stem, 0/250F & -20/120C

Description

Featuring a 4-inch stem, this Cole-Parmer bimetal thermometer provides a mid-length immersion option for various monitoring tasks. It is built around a 3-inch dial with a back connection for mounting. The temperature range is 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius, applicable to water-based systems, environmental chambers, and general equipment. The longer stem, compared to the 2.5-inch models, can improve thermal response and accuracy in certain fluids. As a purely mechanical device, it uses a bimetal coil to indicate temperature without needing external power or calibration under normal use. This instrument serves as a durable, easy-to-read indicator for laboratories, pilot plants, or maintenance applications requiring a reliable temperature readout.
