United Scientific Supplies THPCF6 Thermometer, Red Liquid, 6", Total Immersion, Dual Scale, -20 To 110 C / 0 to 230 F

Features:

• 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.
• These thermometers all have 6 to 7mm outer diameters, and the bulbs have equal or smaller diameters than the stems.
• 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.
