It should not be inclined and can be partially immersed. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances. Recovered from: labcompare.com, Brown G. (2019). The laboratory thermometer is also used in order to control and regulate at a certain temperature the development of different processes or chemical reactions, such as enzymatic determinations, for example. There are other types of more specialized thermometers, such as radiation, which is used to measure the temperature of substances with which it is convenient not to come into contact. The fundamental use of the laboratory thermometer is to measure the temperature with high precision of different substances, whether they are in liquid , solid or gaseous states. These include partial immersion, total immersion, liquid filled, digital and dial thermometers. Its accuracy and precision are characterized by being superior to those of other thermometers. Traditional thermometers use thermometric liquids (i.e., alcohol, mercury) to measure temperature in body cavities -- orally, rectally, vaginally -- or at other axillary points, such as the underarm 1 2. This is because the temperature of the walls or the bottom in general is usually higher than that of the material contained. Laboratory Thermometer. The bulb must be kept within the substance or material while the temperature is required to be measured. For its use it has to be in contact with the substance to be measured, since it does not maintain the temperature reached like clinical thermometers. Inside it contains the stem or capillary through which the mercury or alcohol travels. -The calibrated laboratory thermometer is used in the verification or calibration processes of another thermometer. Maintenance and care is essential, like all laboratory equipment, and must be calibrated to avoid errors in its use. (A) In a thermometer is used to measure the liquid temperature, the correct method is as follows: 1. These types of thermometers are not very affordable because of the cost. The thermometer needs to be very clean before use. The function of the bulb is to contain the thermometric substance. Because of their construction, and their expense, it is important to know how to properly use a lab thermometer without breaking it. There are materials that respond to different temperatures, such as some metals, eg mercury (liquid substance). Laboratory Thermometer: Characteristics, What It Is For, Use, Examples, Lifepersona.com. Recovered from: lifepersona.com, Wikipedia. With the laboratory thermometer you can determine temperatures that vary within a wide range: from -10 ° C to 200 or even 357 ° C approximately. For these purposes, thermometers are used in industry, in quality control laboratories, in experimentation laboratories or in diagnostic routines. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. Join now. As the mercury or alcohol traverses the numerical scale in proportion to the heat it receives, the temperature can be accurately determined. -It is required to measure the maximum and minimum temperatures of certain environments or physical spaces in which it is important to maintain sterile working conditions. -Used to determine the boiling point of substances, the freezing point, or to verify the temperature of solvents. There are thermometers that have alcohol dyed red inside in order to facilitate the observation of the mark that reaches the temperature. They are resistant to temperature fluctuations, since in their elaboration they are subjected to processes such as thermal tempering. -The laboratory thermometer is used to measure the temperature in different processes of monitoring experiments, testing materials, among others. The most common use is that of liquid in glass (upper image), which has a temperature sensor or thermometric substance, which expands or contracts with the increase or decrease in temperature. Physics, chemistry, planetary science, and more are represented by these bloggers. This valve causes the mercury or alcohol to slowly sink or return to the bulb. They are not suitable for measuring body temperatures. using thermometers in the laboratory setting. It can be partially or fully immersed in the substance being measured. Very easy to use and highly portable Probes will vary in size, material, and manoeuvrability Wired probe thermometers are similar to fixed probe thermometers, the difference being that the probe is attached to the thermometer via a wire. Join now. It should not be removed for the reading process as the temperature would fluctuate rapidly reflecting that of the surrounding medium. The nature of the investigation will determine what type of laboratory thermometer should be used, since there are digital, infrared thermometers, among others. Log in. An example of this is alcohol dyed red or mercury, among others depending on the type of thermometer. Log in. Using this ring, the thermometer can be held to keep it immersed during the measurement process or test. (sf). (sf). It is the part that must be in contact with the solution to be measured. -It is an instrument of mandatory presence in the different research laboratories, quality control, sample processing, among many more. Some examples of its use are listed to finish: -The laboratory thermometer is used to measure the temperature in different processes of monitoring experiments, testing materials, among others. Being able to measure the temperature through a thermometer, it can be controlled. The laboratory thermometer is characterized in that it does not have a valve or connection folds between the bulb and the stem. Recovered from: differencebetween.net. Thermometer: Clinical & Laboratory Thermometer. An infrared thermometer helps you identify temperature difference and take necessary actions. Your email address will not be published. There are several characteristics that it has and the following stand out: The most commonly used laboratory thermometer is a glass tube about 30 cm long. It ranges from -10˚C to 110˚C. Recovered from: byjus.com, Mini Physics (2015). There are several different types of thermometers used in the laboratory.
