What is the immersion line on a thermometer?
The immersion line is a quick and easy visual indication to the user. The thermometer should be immersed to this line for correct temperature indication. The reverse of the thermometer should have the inscription “76MM IMM” (or as appropriate). Partial immersion thermometers are usually easy to identify.
What is a 76MM immersion thermometer?
Partial Immersion Non-Mercury Thermometers Thermometer has a white back and a 6 to 7mm outer diameter, and is calibrated for 76mm (3″) immersion. Related Products: Partial Immersion Thermometer.
What is the difference between a total immersion and partial immersion thermometer?
Types of Glass Thermometers Partial Immersion thermometers are immersed in the fluid to the specified immersion depth. The remaining (emergent) portion of the stem is exposed to the air. Total Immersion thermometers need to be immersed to the liquid temperature mark on the thermometer.
How do you measure the temperature of a material?
Measuring temperature is usually done using thermometers or thermocouples. Thermometers, usually made of glass, contain a narrow capillary tube and a liquid whose density changes predictably with temperature. The density of the material determines the volume it will occupy.
What is a partial immersion thermometer?
Partial Immersion thermometers are immersed in the fluid to the specified immersion depth. The remaining (emergent) portion of the stem is exposed to the air. Total Immersion thermometers need to be immersed to the liquid temperature mark on the thermometer.
What are liquid in glass thermometers?
Usually, mercury and petrolate are the most common fluids in this kind of thermometer. Mercury and petrolate usually can measure temperature in a range of −40 to +900°C and −200 to +260°C, respectively [2].
How do I know if my thermometer is working?
Insert the thermometer stem at least an inch deep in the ice water without letting the stem touch the glass. Wait for the thermometer to register; this usually takes a minute or less. The thermometer is accurate if it registers 32° F or 0° C. (My three thermometers are within 1 degree of accuracy at this end.)
