Because it is necessary to know the range of temperature, the accuracy, the recommended depth for immersion, the filling liquid, etc.
the thermometers which are used to find your temperature
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.

Most thermometers used to contain Mercury until it was found to be toxic.
We ca use thermometers, thermocouples, resistance thermometers, pyrometers etc.
One is Fahrenheit and the other is Celsius. Such thermometers are designed to be marketed to multiple countries.
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.
It should be.

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 For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
the title the date
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
