United Scientific™ Thermometer, Red Liquid, 12in, Total Immersion, -20 To 110 C

Student-grade total immersion thermometer with a temperature range of -20° – 110°C. Contains a kerosene-based column with red dye. The thermometer measures 12" long with an outer diameter of 6-7mm. Full immersion thermometers need to be submerged deep enough so the desired temperature is at the meniscus. For example, if you wish to measure the temperature of a hot water bath to make sure it is 100°C, then you need to submerge the thermometer up to the 100°C mark. (1 per EA )
