Electronic thermometers and standard thermometers are equally accurate. In terms of reliability, the standard thermometer wins. Why? Because it doesn't have any batteries to go dead.
The temperature range on a thermometer can vary depending on the type and purpose of the thermometer. Common temperature ranges include -50°C to 150°C for a standard household thermometer and up to 1000°C for specialized industrial thermometers. Digital thermometers can have wider ranges, such as -50°C to 300°C.
The width of a thermometer can vary depending on the specific model and design. However, most standard thermometers have a width ranging from about 1 to 2 inches.
Having a standard thermometer is important for ensuring accuracy and consistency in temperature measurements. Standard thermometers are calibrated to a known reference point, which helps in maintaining consistent measurements across different instruments and settings. This is essential for reliable data comparison, quality control, and scientific research.
The weight of a thermometer can vary depending on its size and design. However, most standard thermometers typically weigh around a few ounces to a couple of pounds.
The lowest temperature on a standard mercury thermometer is typically around -40 degrees Celsius or Fahrenheit, depending on the specific model. Some digital thermometers can register even lower temperatures.
Thermometers are calibrated to ensure accuracy in measuring temperature. Calibration involves comparing the readings of a thermometer to a known standard to verify its correctness and make any necessary adjustments. This helps maintain the reliability and precision of temperature measurements for various applications.
For a basic design of thermometers would base on the principle of thermal expansion, either using air in syringe expand and contract with temperature to indicate the scale or using liquid filled into capillary and mark the scale according to a standard thermometer.
Some pool thermometers do contain mercury, but there are alternatives available that use different substances like alcohol or digital sensors. If you are concerned about the presence of mercury in a pool thermometer, look for options that explicitly state they are mercury-free.

1) Place thermometer perpendicular to the floor and against the wall. 2) Make a mark on the wall at the top of the thermometer. 3) Shift thermometer up so bottom is at mark. 4) Repeat 2) and 3) until close to the ceiling. 5) Shift thermometer up until it touches ceiling and mark location of highest mark on thermometer to determine fraction of thermometer length for last segment. This would give the height of the room in units of "thermometers". This is not a standard unit of measurement, but it is a measurement. If you desire a more standard unit like centimeters, then measure the length of the thermometer and multiply by height of the room in "thermometers". However, you didn't say whether you had a ruler for measuring the thermometer. As as alternative, you could look up the length of the thermometer in the catalog from which it was purchased.
The liquid metal in many thermometer is mercury (Hg).
The highest reading on a typical thermometer is typically 100 degrees Celsius or 212 degrees Fahrenheit, which represents the boiling point of water at standard atmospheric pressure. Some specialized thermometers can measure higher temperatures depending on their design and purpose.
