Feature

●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
●Partial immersion thermometers are useful if you have a shallow container which holds the substance to be measured


Description

Red spirit-filled thermometers provide increased safety and economic pricing. They contain a petroleum-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.
