The freezing point of the liquid used must be low. Factors that increase range would at the same time reduce its sensitivity. Thermometers such as mercury thermometers, alcohol in glass thermometer, constant pressure gas thermometers, and platinum resistance thermometers are designed on the basis of technology. For the first time I am watching education with visualising. Post was not sent - check your email addresses! This means, if the heat is more, the temperature is more than well. Laboratory thermometers are capable of accurately measuring temperature variations in a variety of mediums, including some caustic to human skin. Also, the number of divisions (shown by smaller marks) between these marks is noted. The narrow bore of the capillary tube is uniform. Laboratory thermometers are capable of accurately measuring temperature variations in a variety of mediums, including some caustic to human skin. The modern mercury thermometer was invented by Fahrenheit. Range is the converse of … The range of a laboratory thermometer is generally from - 20 o C (Fig-3). The thermometer should be held at eye level to make reading easier. It ranges from -10˚C to 110˚C. Watch the video below to understand the effect of temperature on matters surrounding us. For mercury thermometer: -39 to 357°C For alcohol-in-glass thermometer: -115 to 78°C; In colder countries, most of its liquid-in-glass thermometers use alcohol and not mercury. Mercury expands quite uniformly over a good range of temperatures. Registering thermometers are designed to hold the temperature indefinitely, so that the thermometer can be removed and read at a later time or in a more convenient place. By definition, the temperature is the measurable extent of hotness or coldness. He is also credited for the invention of the mercury-in-glass thermometer. It is a mathematical representation of heat. The colour of the alcohol should be bright. the bigger mark reads 10 and the number of division is 5, then each division reads the value equal to 10/5 = 20. If the thermometer reading is 32℉ or 0℃, then the thermometer is said to be accurate. Laboratory Thermometer Laboratory thermometers cannot be used for clinical purposes because such thermometers read temperatures ranging from -10 oC to 110 oC, which is very high as compared to the human body temperature range. Small expansion of the liquid in the liquid bulb will cause a big change in the length of the liquid thread in the capillary tube as it is made narrow. A few other helpful tips for thermometer use are as follows: • Facilities need to make sure they record temperatures daily or in some cases, twice a day, according to your SOP. Your email address will not be published. It is given a few jerks. Mercury is in a liquid state at room temperature and has the highest coefficient of expansion. The tip of the thermometer should be placed inside the ear pointing towards the nose. Because of their construction, and their expense, it is important to know how to properly use a lab thermometer without breaking it. Here, we will discuss the two types of thermometers, namely, clinical thermometer and laboratory thermometer. But how do we measure temperature? We use a device called thermometer to measure the temperature of any object. Following are the different types of thermometers that we use on a daily basis: Clinical thermometers are meant for clinical purposes. Your email address will not be published. Range is the converse of sensitivity, i.e., the longer the range, the lower is its sensitivity. The normal ear temperature in adults is 37.5℃. For e.g. Because of their construction, and their expense, it is important to know how to properly use a lab thermometer without breaking it. The thermometer is then kept under the tongue or under the arms in order to get the reading on the thermometer. Reading a glass thermometer. Made with | 2010 - 2020 | Mini Physics |. The range is limited by the freezing and boiling points of liquid. Note: Clinical thermometers must be sterilized before use for the safe and clean check-up. If you spot any errors or want to suggest improvements, please contact us. The thermometer is made relatively small so that it is portable and cheap. Since mercury is a toxic element, thus these thermometers have been replaced by digital thermometers nowadays. Laboratory thermometers. Mercury reacts quickly to the temperature changes whereas alcohol reacts slowly. What an app this is, mind blowing. The normal human body temperature is 37˚C; which can fluctuate between the ranges 35˚C to 42˚C. We note the value of the bigger mark that the mercury thread has crossed (which is 98 in the Fig.4 Example 1). Hence, the temperature reading is 98 + (3×2) = 98.6. Fig-3. This kind is still popular where people like to read temperature from a distance. There are different units to measure temperatures, like Celsius (˚C), Kelvin (K), and Fahrenheit (˚F). Let us now learn how this thermometer … You would need this information to read the thermometer correctly. The bulb is made relatively larger than its bore to contain more of the liquid, so as to improve sensitivity. Daniel Gabriel Fahrenheit is considered to be the father of thermometer. Remove the thermometer from the ear and clean the tip with cotton and alcohol. The information captured is sent to a microchip that processes it and gets displayed numerically on the digital screen. Facts about Laboratory Thermometer 5: scale. We make sure that it falls below the 37⁰C mark or the 98⁰F mark, the normal human body temperature. Gr8 help…seriously..^-^.. C Reading the Fahrenheit thermometer. The answer to that is temperature. thanks1. Then the number of the division of the mercury thread has crossed is noted (3 in this case). As the liquid is contained in a thin-walled, small glass bulb, it will be more responsive (faster response) to heat. Facts about Laboratory Thermometer 6: the today’s scale. Place the tip of the thermometer under the armpit. He was a German physicist who dedicated his life to science and inventions. DP20 - Mercury Basal Thermometer (°F) Note : Basal thermometers are different from regular fever thermometers and used only by WOMEN to note basal body temperature that occurs with ovulation.
