The results are displayed via color changes in the cholesteric liquid material the liquid crystal thermometer is made from. The cholesteric liquid crystals, which, depending on the concentration at different temperature, assume a different color, are responsible for the measurement of temperature. 60 to 89°C ±2°C Liquid crystal thermometers portray temperatures as colors and can be used to follow temperature changes caused by heat flow. It does not indicate core temperature. Liquid Crystal Thermometer Instructions for Use In medical applications, liquid crystal thermometers may be used to read body temperature by placing them against the forehead. Today we take advantage of this ‘usual’ state and use the properties of liquid crystals for many new technologies such as liquid crystal displays (LCDs), which are found in wristwatches, computer screens, large digital clocks and even thermometers. The liquid crystal thermometer allows measuring the temperature of a solid object surface, and the human body, without providing a corresponding electrical signal, making use of special material (heat-sensitive, thermochromic liquid crystal) contained in plastic strips, which are placed against the object or skin surface and that change their color while absorbing heat. Adhesive & Carrier Covering Film Hobbyists who keep tropical fish or exotic pets, such as reptiles and amphibians, have also adopted this type of thermometer as an important part of their equipment. Please ask for details. The color changes are reversible and the reflected colors will be observed in the reverse order upon cooling. 10-50µ Step 7. This causes the temperature event to appear green. Option: Use the infrared thermometer to record the temperature. It’s simply a matter of watching the liquid crystal display until the colors stop changing. We offer a wide range of liquid crystal thermometers as stock products, but also offer literally thousands of custom products for your label. 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. Liquid crystals, which have been used in items like mood rings, have proven to be a safe and reliable thermometer for our cold-blooded friends. LCs can be formulated to change temperature from -22 to +248ºF (-30 to 120ºC), and can be sensitive enough to detect changes as small as 0.2ºF. Disposable Encapsulated liquid crystal technology, displays accurate temperature … 100 Thermometers … conclusively that liquid crystals exist and have a special physical state. LCs start black below their temperature range, go through the colors of a rainbow, and back to black again above the temperature range. Which of the following thermometers can respond quickly to small temperature changes and are used in small or precise locations? KwikTemp’s forehead thermometers offer a fast, accurate way to monitor core body temperatures and take prompt preventive action. 75µ. One of the more common thermometer types in use today is an adhesive strip which attaches to the outer surface of bottles or laboratory equipment and produces accurate readings of the containers temperature. You can obtain an accurate temperature in about 15 seconds. (THM210) Liquid crystal strip thermometer. Color Sequence: Black » Red » Green » Blue (25-30ºC / 77-86ºF) Cold Activated Graphics are used on labels and packaging to create a color change when cooled. Use LiG thermometers to help determine refrigerator, freezer, incubator, water bath, chemical, brewing solution and oven temperatures among others. LCs are reversible in that they can be used over and over again. If kept out of UV light and away from high temperatures and strong solvents, LC products will last for years. Amazon's Choice for Liquid Crystal Thermometer Stick On Thermometer Strip, Digital Temperature Display for Fermenting, Brewing, Wine, Beer, Kombucha or … Disposable Forehead Thermometer FeverScan™ 35 to 41 °C / 94 to 105 °F Line Indicator Display.
