Mercury is often used in the laboratory thermometer because it has unique physical properties. Laboratory thermometer: is used to measure the temperature of all things, except the human body. Never hold the thermometer by the bulb while reading it. The word ‘thermometer’ includes ‘thermos’ of heat and ‘meter’ of measuring, of determining. electronic thermometer a clinical thermometer that uses a sensor based on thermistors, solid-state electronic devices whose electrical characteristics change with temperature. The annual check requires the user to check a reference or NIST thermometer at 0 ºC ( Ice point) each year by immersing the NIST thermometer into a slush bath of distilled water. What an app this is, mind blowing. As regards the mercury-filled devices, a clinical thermometer usually has kinks that prevent the backflow of mercury. The temperature range is from 35°C to 42°C. 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. Digital Thermometers for Laboratory and Field Materials Testing. It is basically used to measure the temperature of humans. Laboratory thermometers are designed small to make it potable. The liquid is contained in a thin-walled glass bulb. Mercury thermometers are being phased out as preference is shifted to other types of thermometers, such as digital, alcohol-filled and organic-based thermometers. (1) A laboratory thermometer is made up of a long glass tube having a thin bore in it. The markings on a clinical and weather thermometer are different, but they work in the same way. Daniel Gabriel Fahrenheit is considered to be the father of thermometer. Many researchers use them to ascertain freezing and boiling points. The thermometer is washed with water at a normal temperature. Following are the different types of thermometers that we use on a daily basis: Clinical thermometers are meant for clinical purposes.
