How does LCD strip thermometers work?
if you are talking about the strips that you put on your forehead it isn't an LCD strip instead there are different thermochromic inks applied to different parts of the strip. when heat is applied to the inks they change colour and with the use of different inks, they change colour at different temperatures because of this, you can see your temperature (: help much?
Different types of thermometers and their uses with pictures?
There are several types of thermometers. Clinical thermometers are used to measure the body temperature of the patient. Ear Thermometers make it an accurate point to measure the body temperature. Pacifier thermometers are used to check the body temperature of babies or infants. Underarm thermometers are kept in the underarms to measure the body temperature. Not to mention the food thermometers that are often used for checking the heat of the oil or pop up to let you know when the meat is done.
What liquid used to be in thermometers?
Most thermometers used to contain Mercury until it was found to be toxic.
How do you accurately measure the temperature of a substance?
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
What liquid used to be in most thermometers?
Most thermometers used to contain mercury until it was found to be toxic.
Are there any other uses for the expansion and contraction of matter?
it is used for bimetallic strip thermometers which is there in refrigerator and oven.
What do forehead thermometers do?
The forehead thermometer is a disposable strip of plastic with liquid crystals embedded into the strip. To take a person's temperature, one places the strip against the person's forehead. The liquid crystals react with the temperature of the skin. After waiting anywhere from a few seconds to a few minutes, depending on the brand, the crystals will change color. The thermometers have a number line that shows the temperature based on the color displayed.
What different kinds of thermometers are there?
There are 34 different types of thermometer that range from alcohol thermometers and ear thermometers to medical thermometers and electrical resistance thermometers.
Give one reason why it is safer to use a plastic strip thermometers?
Because if you use a glass thermometer, there is more chance of disease or micro organisms being spread.

What where the first thermometers?
Mecury thermometers
What is the advantage of bimetal thermometer?
A biometallic thermometer measures temperature. It uses a differential thermal expansion of metals that are bonded together into a strip. Another name for these thermometers is differential thermometer.
How are mercury thermometers used today?
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
How does a thermometer detect temperature?
Matter generally expands as it warms, and contracts as it cools. In liquid thermometers, as the liquid heats and expands, it is directed up a tube with markings to show the exact amount of expansion. In Bi-metal thermometers, there is a strip of two different metals pressed together. These metals expand and contract at different rates. As a result, the strip will coil and uncoil with the rise and fall of the temperature. A needle attached to this coil can show the temperature.
What is liquid metal was used in thermometersr?
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).
Are digital and clinical thermometers same?
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
Different types of thermometers?
Celsius and Fahrenheit Thermometers Clinical Thermometers Ear (Tympanic) thermometers Pacifier Thermometers Underarm or Oral Thermometers Food Thermometers Outdoor Thermometers Mechanism of Different Types of Thermometers Mercury and Alcohol Thermometers Digital Thermometers Alcohol thermometer Beckmann differential thermometer Bi-metal mechanical thermometer Electrical resistance thermometer Galileo thermometer Infrared thermometer Liquid Crystal Thermometer Medical thermometer (e.g. oral thermometer, rectal thermometer, basal thermometer) Mercury-in-glass thermometer
