Cole-Parmer Spirit-Filled Thermometer, 50 to 250 °C

Description

This laboratory thermometer from Cole-Parmer provides temperature measurement from 50 to 250 degrees Celsius. Its operation relies on the thermal expansion of a spirit fluid within a sealed glass system, causing the liquid column to rise or fall along an engraved scale for a direct visual reading. As an analog instrument requiring no external power, it is a fundamental tool for monitoring temperatures in applications like heating mantles, oil baths, or other liquid media. The glass construction is intended for immersion in non-corrosive substances. Users should handle it with care to preserve its calibration and prevent damage. This type of thermometer is valued in many labs for its simplicity, reliability, and straightforward interpretation of temperature data.
