The mean rectal tempera … – Two color/temperature are used for specifying a given LC. A liquid crystal thermometer is a type of medical thermometers which are designed for defining body temperature changes. A liquid crystal thermometer, temperature strip or plastic strip thermometer is a type of thermometer that contains heat-sensitive (thermochromic) liquid crystals in a plastic strip that change colour to indicate different temperatures. This type is the oldest and most common kind of thermometer. Liquid crystal thermometer strips are being used for thermal mapping and other industrial applications where custom inexpensive temperature monitoring is warranted. Liquid Crystal Thermography What are thermochromic liquid crystals (TLC)? Many older thermometers contained mercury. These thermometers are used for a variety of applications, from reading the body temperature of a patient to making accurate measurements of liquid and air temperature ranges in chemical laboratories or breweries. Liquid crystal thermometers portray temperatures as colors and can be used to follow temperature changes caused by heat flow. Other articles where Liquid thermometer is discussed: thermometer: Liquid thermometers were once the most common type in use. In medical applications, liquid crystal thermometers may be used to read body temperature by placing them against the forehead. The Exo-Terra Liquid Crystal Thermometer contains an extended upper range (68°F to 107°F) for heat-loving reptiles, and is horizontally oriented with a liquid crystal display for easy reading. The low cost of the instrument, coupled with the ability to accurately measure a wide range of temperatures, makes this thermometer an integral part of many manufacturing and medical processes. The constant-volume gas thermometer – it contains a gas; when the temperature rises, the pressure increases. [4], "Basics of Home Brewing: What is a liquid crystal thermometer? When the temperature changes, the liquid … The color changes are reversible, while the re-use of this type of thermometer may occur after about a minute from the previous reading.
