Thermometer, Red Liquid, 6", Total Immer (Discontinued)

Student-grade total immersion thermometer with a temperature range of -20° TO 110 C° / 0° TO 235° F. 6" Red spirit-filled thermometers provide increased safety and economic pricing. They contain a kerosene-based column with red dye, which is significantly safer than mercury. 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.
