How the thermometer works
Nettet7. jul. 2024 · Set the thermometers in front of the fan as before. After 5 minutes record the “wet bulb” temperature reading and the “dry bulb” temperature reading. 4. To determine relative humidity subtract the lower “wet bulb” temperature from the higher “dry bulb ” temperature to determine the difference and compare to the chart. NettetThe thermometer operates on Stefan’s law. This device measures the temperature from the heat radiation emitted by the objects. These thermometers can be used without being in contact with the objects. A pyrometer Thermometer measures a temperature greater than 2000 k.

Similar to visible light, it is also possible to focus, reflect, or absorb infrared light. Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile. The thermopile is nothing but thermocouples connected in series or parallel. maple view surgery churchill redditch
