Because it is necessary to know the range of temperature, the accuracy, the recommended depth for immersion, the filling liquid, etc.
No, oral mercury thermometers do not expire. However, they should be handled and stored properly to ensure accurate readings. Over time, the calibration of the thermometer may shift, leading to inaccurate readings.
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.
There are no convenient alternatives to using a thermometer to measure body temperature.
Most thermometers used to contain mercury until it was found to be toxic.
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
It should be.
There are 34 different types of thermometer that range from alcohol thermometers and ear thermometers to medical thermometers and electrical resistance thermometers.
Mercury is highly poisonous and should not be used in milk production. The only place where mercury might be used in milk production is in mercury thermometers and where possible, these should be replaced with alcohol thermometers.
Assuming you're talking about a glass thermometer, each mark or 'tick' on the thermometer stands for a 5 degree increase/decrease. Most thermometers should have their degrees labeled in increments of 10, with one mark in between symbolizing an increment of 5, which is (most of the time) unmarked.

Mecury thermometers
All genetically modified should be labeled so consumers can make their own decision as to whether or not to purchase them.
The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
Start at the box labeled Go.
No, mercury is not present in all types of thermometers. While mercury thermometers are common, other types such as digital thermometers and infrared thermometers do not contain mercury. Mercury thermometers are being phased out due to environmental concerns.
A thermometer is used to measure temperature. There are various types of thermometers such as digital thermometers, mercury thermometers, infrared thermometers, and thermocouples.
