Types of thermometer pdf
There are six different types of thermometers. They include digital thermometers, digital ear thermometers, digital pacifier thermometers, temporal artery thermometers, temperature strips and mercury thermometers. various types of sensors and regulators. Temperature Sensors Temperature sensors are devices used to measure the temperature of a medium. There are 2 kinds on temperature sensors: 1) contact sensors and 2) noncontact sensors. However, the 3 main types are thermometers, resistance temperature detectors, and thermocouples. Rectal thermometers are the most accurate. If suitable, you should try to use either of these methods, especially for younger children. When a baby is an infant, having a temperature reading that’ s even a few degrees off might make the difference of needing a trip to the hospital or not. Oral thermometers are also accurate. What are the different types of thermometers? Liquid- in- glass thermometers, bimetal thermometers, resistance thermometers, infrared thermometers, gas thermometers and liquid- crystal thermometers are a few examples of types of thermometers. Various types of thermometers exist for multiple purposes and uses. The basic use for a thermometer is to measure changes in temperature.
The best type of thermometer — or the best place to insert the thermometer, in some cases — depends on your child' s age. Birth to 3 months. Use a regular digital thermometer to take a rectal temperature. New research suggests that a temporal artery thermometer might also provide accurate readings in newborns. What thermometer is most accurate? temperature measurements along with the definition of thermodynamic temperature in 2. 1 and it is defined based on several fixed points of temperature ( defining fixed points) such as phase transition temperature of substance and using several types of stable thermometers. First international temperature scale was established in 1927. Liquid- in- GlassThermometry JacquelynA. Wise InstituteforBasicStandards NationalBureauofStandards Washington, D.
