What else can I help you with?
Whether the body temperature can be measured by keeping the thermometer at some place other than mouth?
Yes, you can measure body temperature by putting the thermometer under your arm (in which case it should measure below 36.5 degrees Celsius.) You can also get ear thermometers, but these work quite differently to regular oral/underarm thermometers. Forehead thermometers are also available.
What type of thermometer has the smallest graduation and would give the most accurate temperature reading?
A platinum resistance thermometer PRT, is the commonest thermometer with high accuracy. It may have a range from -200 C to +1 000 C, and an accuracy of up to 0.001 C provided it is installed in an appropriate measuring configuration. Similar thermometers are made from nickel (and other metals), but their cost benefit is obtained at the expense of range and accuracy. In either case, the metal must have been manufactured with the end application in mind. The standard against which high accuracy thermometers should be measured is that of the International Temperature Scale, ITS-90. This specifies a number of reference calibration points such as the triple point of various substances, and of the freezing points of others.
What is the difference between a chocolate thermometer and a regular thermometer?
A chocolate thermometer and a regular thermometer differ from each other by its size and sturdiness. The chocolate thermometer are much bigger than the regular thermometer so that it can withstand the extreme heat. The normal thermometer can withstand less heat than the other one.
What is the function of the laboratory thermometer?
A Thermometer is a Laboratory Equipment that measures temperature.
What are the units used for a thermometer?
Temperature is usually express in one of 4 units: °C: Celsius (aka Centigrade) - most common °F: Fahrenheit - in the USA and some other places K: Kelvin - mostly for scientific and engineering calculations. Has the same intervals as Celsius but has a different starting point: 0 °C is 273.15 K. Note that unlike the other temperature units, the abbreviation for Kelvin does not use the ° "degree" symbol °R: Rankine - used in engineering and sometimes science where Fahrenheit is the usual unit of temperature. Like Kelvin, it starts at 0° at the "absolute zero" of thermodynamics. 0 °F corresponds to 491.67 °R.
How inaccurate is underarm thermometer?
Underarm thermometers can be less accurate than other types of thermometers, such as oral or rectal thermometers. They can be affected by factors like ambient temperature, sweating, and clothing. For the most accurate reading, it's best to use a thermometer in the mouth, rectum, or ear.
Are all instant read meat thermometer devices digital?
Instant read meat thermometers are always digital. The other syle of meat thermometer is analog and it takes time to reach the temperature reading after insertion into the meat.
What are the cons of an infrared thermometer?
Some cons of an infrared thermometer are that they can be less accurate than traditional contact thermometers, especially at far distances or on reflective surfaces. They also may not provide as precise temperature readings as other types of thermometers. Additionally, they require a direct line of sight to the target area for accurate measurements.
What type of thermometer gives the least accurate reading of all thermometers?
Infrared thermometers can give less accurate readings compared to other types of thermometers, especially when measuring the temperature of objects that are very shiny or reflective. This is because they measure the infrared radiation emitted by an object, which can be affected by its surface properties.
What are the benefits of using a quick read rectal thermometer compared to other types of thermometers for accurate temperature measurement?
A quick read rectal thermometer provides more accurate temperature measurements compared to other types of thermometers because it measures the internal body temperature, which is more reliable for detecting fever or illness. Additionally, it provides faster results, making it convenient for quick and accurate temperature monitoring.
What is the difference between clinical thermometer and laboratory thermometer?
Laboratory thermometers can measure wide variety of temperature, whereas a clinical thermometer has a range between 95 to 105 Fahrenheit. Clinical thermometers are made to be used in a hospital to accurately determinebody temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park". Clinical thermometer may have mercury but lab thermometers usually have alcohol .
How do you measure an objects temperature?
You can measure an object's temperature using a thermometer. Make sure the thermometer is in direct contact with the object to get an accurate reading. Other methods include using infrared thermometers or thermal imaging cameras.
Why gas thermometer is more sensitive then liquid thermometer?
Gas thermometers are more sensitive than liquid thermometers because gases expand and contract more easily in response to changes in temperature. This results in faster and more accurate readings. Liquid thermometers, on the other hand, have slower response times due to the higher density and lower thermal expansion coefficient of liquids.
How is digital thermometer is better than conventional thermometers?
Digital thermometers have the advantage that they are simpler to read and the electrical components used to make them are cheap, accurate, and reliable. An analog thermometer may have ambiguity when you read it because of angle of viewing, difficulty seeing, or many other things while a digital thermometer clearly outputs a single unambiguous number.
Is there mercury in thermometers today?
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
Difference between clinical thermometer and other thermometer?
You would likely have different ranges and accuracies for different thermometers. I'm using Fahrenheit. Many newer thermometers would be in Celsius, including those used in hospitals/clinics, or in other parts of the world outside of the USA. A clinical thermometer might read from about 80°F to 110°F, and would be accurate to 1/10 or 2/10 degrees. They can be digital, mercury, or even plastic disposable. They normally have a method to lock in the maximum temperature (like the old ones that you had to shake down). Modern clinical thermometers will either have a disposable plastic cover for the non-disposable variety, or will be 100% disposable. Ocular ear thermometers are a new type of infra-red thermometers. A household thermometer might read from -20°F to 120°F, and might only be accurate to 1 or 2 degrees. If the thermometer is a glass thermometer, the scale is never written on the actual thermometer. A scientific thermometer might have a range up to the boiling point of water... is often in Celsius (-10°C to 110°C), and accurate to a degree Celsius (2 degrees Fahrenheit) or so. A cooking thermometer might have a range of 100°F to 500°F. There may be some glass (or disposable) cooking thermometers, but many are also metal for durability.
Which liquid would be better in the thermometer. why?
Mercury is commonly used in thermometers due to its high thermal conductivity and visibility in the narrow tube, allowing for accurate temperature readings. Alcohol thermometers, on the other hand, are safer and less toxic compared to mercury thermometers. The choice of liquid depends on the specific use and safety considerations.
